  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

  3. 2. Evaluation of hardware and firmware for a Data Readout system of the PANDA Electro-Magnetic Calorimeter

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Ehsan Noorzaei; [2023]
