22. Simulation and Electrical Evaluation of 4H-SiC Junction Field Effect Transistors and Junction Barrier Schottky Diodes with Buried Grids
Abstract : Silicon carbide (SiC) has higher breakdown field strength than silicon (Si), which enables thinner and more highly doped drift layers compared to Si. Consequently, the power losses can be reduced compared to Si-based power conversion systems. Moreover, SiC allows the power conversion systems to operate at high temperatures up to 250 oC. READ MORE

23. Electromechanical Interactions in Shuttle Systems and Carbon Nanotube Relays
Abstract : In this thesis we theoretically investigate two kinds of nanoscale systems where there is a strong electromechanical coupling, i.e. an intricate relation between the Coulomb forces that can appear in these systems and the displacements of parts of the systems that they cause. READ MORE

24. Design and Fabrication of Silicon Carbide RF MOSFET for L- and S-band applications
Abstract : This thesis describes realisation of 4H-SiC radio-frequency metal-oxide-semiconductor field effect transistors (RF MOSFETs). Such transistors are in principle very attractive devices for high power and high frequency electronics. They are intended as a direct replacement for their silicon counterparts, offering higher power. READ MORE
