11. Designs and simulations of silicon-based microphotonic devices
Abstract : The characteristics of a silicon-on-insulator (SOI) rib waveguide, including the bending loss of a multimode bent waveguide and the birefringence of a rib waveguide, are analyzed by using a finite-difference method (FDM). Based on a detailed analysis for a multimode bent waveguide, an appropriately designed multimode bent waveguide for reducing effectively the bending loss of the fundamental mode is realized.

12. Influence of Electron Charge States in Nanoelectronic Building Blocks
Abstract : The continued efforts to improve performance and decrease size of semiconductor logic devices are facing serious challenges. In order to further develop one of the most important nanoelectronic building blocks, the metal-oxide-semiconductor field-effect-transistor (MOSFET), several major problems have to be solved.

13. Schottky Contacs on Silicon Nanowires
Abstract : This thesis demonstrates the effect of charge on Schottky barrier height for metal contacts at the end surfaces of silicon nanowires. It is shown, by measurements and analytical models, how the effective electron barrier is lowered by a positive charge introduced into an oxide embedding the wire. READ MORE

14. Integration of graphene into MEMS and NEMS for sensing applications
Abstract : This thesis presents a novel approach to integrate chemical vapor deposition (CVD) graphene into silicon micro- and nanoelectromechanical systems (MEMS/NEMS) to fabricate different graphene based MEMS/NEMS structures and explore mechanical properties of graphene as well as their applications such as acceleration sensing, humidity sensing and CO2 sensing. The thesis also presents a novel method of characterization of CVD graphene grain boundary based defects. READ MORE
