16. Growth and characterization of SiC and GaN
Sammanfattning : At present, focus of the SiC crystal growth development is on improving the crystalline quality without polytype inclusions, micropipes and the occurrence of extended defects. The purity of the grown material, as well as intentional doping must be well controlled and the processes understood. LÄS MER
17. Growth and Characterization of Ti-Si-N Hard Coatings
Sammanfattning : Metastable (Ti,Si)N alloy and TiN/SiNx multilayer thin solid films as well as SiNx/TiN surfaces have been explored. Cubic Ti1-xSixN (0≤x≤0. LÄS MER
18. CVD Growth of Silicon Carbide for High Frequency Applications
Sammanfattning : Silicon Carbide (SiC) is an important wide band gap semiconductor with outstanding electronic properties. With figures of merit far better than silicon, SiC is believed to replace and outcompete silicon in many applications using high frequencies, high voltage and high temperatures. LÄS MER
19. Growth Dynamics of Semiconductor Nanostructures by MOCVD
Sammanfattning : Semiconductors and related low-dimensional nanostructures are extremely important in the modern world. They have been extensively studied and applied in industry/military areas such as ultraviolet optoelectronics, light emitting diodes, quantum-dot photodetectors and lasers. LÄS MER
20. Experiments and Theoretical Modeling of Fullerene-like CNx and CPx Thin Film Structures
Sammanfattning : This thesis concerns the materials science of carbon-based fullerene-like structures as a basis for the improvement of the applicability of FL-CNx protective thin films. In particular, structural origins of mechanical properties of FL-CNx coatings and water adsorption on their surface were investigated, both of which are critical parameters for their application as, e.
