  7. 5. Fabrication of Integrated HBV Multipliers for THz Generation

    Författare :Aleksandra Malko; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon.; indium phosphide; frequency multipliers; power sensors; Epitaxial transfer; heterostructure barrier varactors;

    Sammanfattning : The main objective of this licentiate thesis is to demonstrate silicon integrated HBV frequency multipliers for THz generation with RF performance comparable with InP technology. The choice of silicon is motivatedby better thermal and mechanical properties, cost and ease of integration compared to III-V semiconductor substrates. LÄS MER
