11. Vapor phase deposition of WO and WC
Abstract : WO3 and WC are two compounds that are widely used for a number of different thin film applications. In this thesis, these compounds have been deposited using two different deposition methods: atomic layer epitaxy (ALE) and chemical vapor deposition (CVD). READ MORE

12. InP based Micromechanics for Vertical-Cavity Micro-Opto-Electro-Mechanical Systems
Abstract : During the past decade, the amount of transmitted data hasbeen boosted due to an increasing use of the World Wide Web(WWW), video and audio transmissions. In the late 90s, thetraditional technology using twisted copper cables was nolonger capable to provide enough transmission capacity for theconstantly increasing data traffic. READ MORE

14. Epitaxial III-V/Si heterojunctions for photonic devices
Abstract : Monolithic integration of III-V materials on silicon is of great interest for efficient electronic-photonic integrated devices and multijunction solar cells on silicon. However, defect formation in the heteroepitaxial layers due to lattice mismatch, thermal mismatch, and polarity mismatch makes it a great challenge. READ MORE

15. Epitaxial growth of semiconductor nanowires
Abstract : This thesis describes the results obtained from investigations carried out on epitaxially grown III-V semiconductor nanowires aimed at improving our understanding of and knowledge on the growth mechanism of nanowires. This is important to be able to control their growth, in order to make future applications possible. READ MORE
