  3. 3. Design and Fabrication of III-V Semiconductor Devices for Millimetre- and Submillimetre Wave Applications

    Författare :Svein M. Nilsen; Chalmers University of Technology; []
    Nyckelord :;

    Sammanfattning : Devices (various types of diodes) have been fabricated in several different III-V semiconductors (AlxGa1-xAs, In1-xGaxAs, and InAs). The III- V compound semiconductors lend themselves well to high frequency applications due to the high electron mobility that can be obtained. LÄS MER
