  1. 1. Heterostructure Diodes for Millimeter Wave Power Generation

    Författare :Hans Grönqvist; Chalmers University of Technology; []
    Nyckelord :Single barrier varactor diode; AlSb barrier; InAs substrate; high frequencies; Resonant Tunneling Diode;

    Sammanfattning : This thesis deals with two types of heterostructure diodes namely the Resonant Tunneling Diode (RTD) and the Single barrier varactor diode (SBV). The RTD is a device for high frequency generation either as a negative reistance oscillators or as a multiplier. Different means to reach high frequencies are outlined. LÄS MER
