    Master-uppsats, KTH/Tillämpad fysik

    Författare :Linnéa Bendrot; [2022]
    Nyckelord :Ohmic contacts; high-electron-mobility transistor; InP; Nb films; cryogenic electronics; low-noise amplifier; quantum computing; transfer length method; superconductivity; contact barrier resistance; Ohmska kontakter; högelektronmobilitetstransistorer; indiumfosfid; niob; tunnfilm; kryogen elektronik; lågbrusförstärkare; kvantdatorer; Transfer Length-metod; supraledning; kontakt- barriärresistans;

    Sammanfattning : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. LÄS MER

  5. 9. Increasing the efficiency of the CERN accelerators by use of Superconducting Magnetic Energy Storage (SMES)

    Master-uppsats, Uppsala universitet/FREIA

    Författare :Joakim Kvarnström; [2021]
    Nyckelord :Energy Storage; Power Conversion; Particle Accelerator; Superconductivity; SMES;

    Sammanfattning : This report explains how an SMES is operated and how SMES systems could be used to increase the efficiency of the CERN Large Hadron Collider (LHC) and the Future Circular Collider (FCC) as well as to reduce the very high power needs of a future Muon Collider (MC). The performance of SMES for other applications and late developments of the technique will also be described. LÄS MER

  7. 10. On the superconducting critical temperature in Eliashberg theory

    Master-uppsats, KTH/Fysik

    Författare :Max Oliveberg; [2021]
    Nyckelord :Eliashberg; Superconductivity; Mathematical Physics; Eliashberg; Supraledning; Matematisk Fysik;

    Sammanfattning : This thesis presents a brief synopsis of the derivations of the BCS and Eliashberg equations. An analytic formula for the critical temperature $T_c$ in Eliashberg theory is derived, which contains a sum of iterative integral corrections. LÄS MER
