  1. 1. Superconducting gates for InP HEMTs

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Sebastian Alveteg; [2023]
    Nyckelord :Cryogenic electronics; HEMT; Superconductors; Applied Physics; Kryogenisk elektronik; HEMT; Supraledare; Tillämpad fysik;

    Sammanfattning : The thesis examines the prospects of using the superconductor NbN as the gatemetal for an InP HEMT. A HEMT or High Electron Mobility Transistor is aheterostructure transistor engineered to reach very high electron mobility. InPHEMTs are used as cryogenic Low Noise Amplifiers (LNAs), which have increasedin demand as quantum computing is scaling up. LÄS MER

  7. 5. Current Distribution in High RF Power Transistors

    Magister-uppsats, Ämnesavdelningen för elektronik

    Författare :Jihad EL-Rashid; Youssef Tawk; [2007]
    Nyckelord :Current Distribution in High RF Power Transistors;

    Sammanfattning : To obtain the power levels required from high RF power transistors, the size of the chip has often to be made so large that inductance of electrical connections inside the package cannot be neglected. This may have the effect that various parts of the transistor chip are not connected exactly parallel, i.e. LÄS MER
