    [pib] High Electron Mobility Transistor (HEMT)

    PIB | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: HEMT

    Mains level: NA

    Indian Scientists from Bangalore have developed a highly reliable, High Electron Mobility Transistor (HEMTs) that is normally OFF the device and can switch currents up to 4A and operates at 600V.

    We cannot deny the possibility of a complex S&T based prelims question. This newscard seems very technical. However many of you might be aware of the p-n junction diodes and conventional transistors.

    What is HEMT?

    • A high electron mobility transistor or HEMT is a type of field-effect transistor (FET) that is used to produce a high performance at microwave frequencies.
    • The HEMT provides a fusion of low noise figure that comes combined with the unique ability to function at very high microwave frequencies.
    • These devices are commonly used in aspects of radiofrequency designs that require high performance at high-frequency levels.
    • They produce a high gain, which makes these transistors very useful as amplifiers. They can switch speeds very rapidly.
    • And finally, they produce very low noise values as the current variations in these transistors are comparatively low.

    Practical applications of HEMT

    • HEMTs are used in applications where microwave millimetre wave communications are conducted.
    • They are also used for radar, imaging, as well as radio astronomy.
    • They are also used in voltage converter applications.
    • These transistors are also ideal as digital on-off switches in integrated circuits, and to be used as amplifiers for huge amounts of current by using a small voltage as a control signal.

    What is the news?

    First-ever indigenous HEMT

    • This first-ever indigenous HEMT device made from gallium nitride (GaN) is useful in electric cars, locomotives, power transmission and other areas requiring high voltage and high-frequency switching.
    • It would reduce the cost of importing such stable and efficient transistors required in power electronics.

    How does it work?

    • Power electronic systems demand high blocking voltage in OFF-state and high current in ON-state for efficient switching performance.
    • Specific transistors called HEMTs made of aluminium gallium nitride/ gallium nitride (AlGaN/GaN) provides an edge over silicon-based transistors as they allow the systems to operate at very high voltages, switch ON and OFF faster, and occupy less space.
    • Commercially available AlGaN/GaN HEMTs use techniques to keep the transistor in a normally OFF state, which affects the stability, performance and reliability of the device.
    • Therefore, to meet this need, researchers have developed a new kind of HEMT, which is in the OFF state by default and works like any other commonly used power transistor.

    Back2Basics: Five Iconic Archaeological Sites

    The government has proposed to develop five archaeological sites as “iconic sites” with onsite museums in Rakhigarhi (Haryana), Hastinapur (Uttar Pradesh), Sivsagar (Assam), Dholavira (Gujarat) and Adichanallur (Tamil Nadu) in the Union Budget 2020-21.

    (1) Rakhigarhi

    *discussed above*

    (2) Hastinapur

    Hastinapur in the Meerut district of Uttar Pradesh finds mention in the Mahabharata and the Puranas. One of the most significant discoveries made at this site was of the “new ceramic industry”, which was named the Painted Grey Ware, which as per the report represented the relics of the early Indo-Aryans.

    (3) Sivasagar

    In Sivasagar (Assam), excavations at the Karenghar (Talatalghar) complex between 2000 and 2003 led to the discovery of buried structures in the north-western and north-eastern side of the complex. Among the structural remains found at the site were ceramic assemblages including vases, vessels, dishes, and bowls, etc. Terracotta smoking pipes were also found.

    (4) Dholavira

    Dholavira in Gujarat is located in the Khadir island of the Rann of Kutch, and like Rakhigarhi is one of the sites where the remains of the Harappan civilization have been found. It is unique because the remains of a complete water system have been found here.

    (5) Adichnallur

    Adichnallur lies in the Thoothukudi district of Tamil Nadu. The urn-burial site was first brought to light during a “haphazard excavation” by a German archaeologist in 1876. Following this, an Englishman Alexander Rae excavated the site between 1889 and 1905.

    From UPSC perspective, the following things are important:

    Prelims level: ONORC

    Mains level: Welfare of the migrant workers

    Seventeen (17) States have successfully operationalised the “One Nation One Ration Card system” with Uttarakhand being the latest State to complete the reform.

    Practice question for mains:

    The ‘One nation one ration card ‘scheme would bring perceptible changes to the lives of India’s internal migrant workers. Comment.

    One Nation One Ration Card

    • This scheme aims to ensure all beneficiaries, especially migrants get ration (wheat, rice and other food grains) across the nation from any Public Distribution System (PDS) shop of their own choice.
    • Under the existing system, a ration cardholder can buy food grains only from the fair price shop (FPS) in the locality where he or she lives.
    • It was also launched with the purpose that no poor person should be deprived of getting subsidised food grains under the food security scheme when they shift from one place to another.
    • It aims to reduce instances of corruption by middlemen and fraudulence in ration cards to avail benefits from different states.

    Who is eligible under this scheme?

    • Any citizen, who is declared under the Below Poverty Line (BPL) category, will be eligible to get the benefit of this scheme across the country.
    • The beneficiaries will be identified on the basis of their Aadhar based identification through the electronic point of sale (PoS) device.
    • All the PDS shops will have the facility of electronic PoS devices.

    Impact on states

    • The reform enables the States to better targeting of beneficiaries, elimination bogus/ duplicate/ineligible cardholders resulting in enhanced welfare and reduced leakage.
    • An additional borrowing limit of 0.25 per cent of the Gross State Domestic Product (GSDP) is allowed to the States only on completion of both of the following actions:
    1. Aadhar Seeding of all the ration cards and beneficiaries in the State
    2. Automation of all the FPSs in the State.

    Back2Basics: Public distribution system (PDS)

    • The public distribution system (PDS) is an Indian food Security System established under the Ministry of Consumer Affairs, Food, and Public Distribution.
    • PDS evolved as a system of management of scarcity through the distribution of food grains at affordable prices.
    • PDS is operated under the joint responsibility of the Central and the State Governments.
    • The Central Government, through the Food Corporation of India (FCI), has assumed the responsibility for procurement, storage, transportation and bulk allocation of food grains to the State Governments.
    • The operational responsibilities including allocation within the State, identification of eligible families, issue of Ration Cards and supervision of the functioning of FPSs etc., rest with the State Governments.
    • Under the PDS, presently the commodities namely wheat, rice, sugar and kerosene are being allocated to the States/UTs for distribution.
    •  Some states/UTs also distribute additional items of mass consumption through PDS outlets such as pulses, edible oils, iodized salt, spices, etc.

    [pib] INS Karanj – A Kalvari Class Submarine

    PIB | Security Issues | Mains Paper 3: Various Security Forces, Agencies & Their Mandates

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: INS Karanj, Various classes of Submarines

    Mains level: NA

    Indian Navy’s third stealth Scorpene-class Submarine INS Karanj has been commissioned into the Indian Navy. It also completed the trials of the Indigenous Air Independent Propulsion (AIP) System jointly developed by Naval Materials Research Laboratory (NMRL) and DRDO.

    In a rare case, we would see a question based on various classes of Indian Submarines in the CSP. However, we can expect a question based on the AIP system in the CSP and CAPF exam.

    INS Karanj

    • INS Karanj is the third submarine of the first batch of six Kalvari-class submarines for the Indian Navy.
    • It is a diesel-electric attack submarine based on the Scorpene-class, designed by French naval defence and energy group DCNS and manufactured by Mazagon Dock Limited, an Indian shipyard in Mumbai.

    What is AIP?

    For this, we have to understand how a submarine works. Traditionally we hear about two types of submarines- Nuclear and Diesel Electric.

    Diesel Electric Submarines

    • While Nuclear Submarines can stay submerged for a prolonged period and remain undetected, Diesel Electric submarines cannot do so, and they must surface after a stipulated time interval.
    • Their Diesel Propulsion would need air to run the engine like any other Vehicle or Aircraft engines and for this, they would need oxygen which is not available underwater.
    • Hence they have to move closer to the surface so that their engines can breathe air through their snorkels.

    So, these diesel turbines charge the batteries available in the submarine and once the batteries are fully charged, the submarine goes underwater where the propeller shaft, as well as other systems, runs on the power stored in the batteries.

    • This makes the Submarine very much vulnerable to threats from Air, Sea or even underwater.
    • Not only has this, but the storage of excessive fuel also reduced the overall performance and weapon holding of the submarine too.

    Why don’t we can induct only the Nuclear Submarines in the Navy?

    • Though nuclear submarines can stay underwater for months, they cannot do so with total stealth.
    • While a diesel-electric submarine (while underwater) is making no noise, Nuclear submarines have a lot of vibrations that are generated from the coolant pumping system of their reactors which must run nonstop.
    • This makes even nuclear submarines vulnerable to depth sonars.
    • Moreover, the manufacturing cost of these submarines is several times higher than those of diesel-electric ones.
    • So, the most effective and commercially viable solution is a diesel-electric submarine with AIP.

    What is AIP, then?

    • Over the years the biggest challenge before the mariners was to ensure that the submarines can sustain underwater for a prolonged time.
    • AIP is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel).
    • While there are different types of AIP systems being pursued internationally, the DRDO has applied fuel cell-based AIP using hydrogen onboard.
    • Fuel cell-based AIP has merits in performance compared to other technologies
    • While the first two submarines (INS Kalvari & INS Khanderi) are equipped with French-made AIPs, the rest of the submarines will be equipped with an Indian system.

    Note: The Project 75I-class submarine is a follow-on of the Project 75 Kalvari-class submarine for the Indian Navy.

    Significance for India

    • With this induction, India has joined the club of six other elites who have the capacity to design and install such complex systems.
    • These countries are France, China, Spain, Sweden, Germany and Russia.
    • Indian AIP system is unique. It is one of the most advanced AIP systems of the world where Fuel Cell technology is used to generate onboard power.
    • With indigenous AIP, submarines can stay underwater for more than 3 weeks in low consumption mode, more than 2 weeks in endurance mode and 2-4 days in max power mode.

    Back2Basics: Various classes of Submarines in India

    In maritime terms, a class of ships is a group of vessels that have the same make, purpose and displacement.

    • Chakra Class: Under a 10-year lease from Russia since 2012
    • Arihant Class: Nuclear-powered ballistic missile submarines
    • Shishumar Class: Diesel-electric attack submarines Indian variant of the Type 209 submarines developed by the German Navy
    • Kalvari Class: Diesel-electric attack submarines designed by French company DCNS
    • Sindhughosh Class: Kilo-class diesel-electric submarines built with the help of Russia
