1. Gallium nitride templates and its related materials for electronic and photonic devices
Sammanfattning : .... LÄS MER
2. 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
3. High-quality InP on Si and concepts for monolithic photonic integration
Sammanfattning : As the age of Moore’s law is drawing to a close, continuing increase in computing performance is becoming increasingly hard‐earned, while demand for bandwidth is insatiable. One way of dealing with this challenge is the integration of active photonic material with Si, allowing high‐speed optical inter‐ and intra‐chip connects on one hand, and the economies of scale of the CMOS industry in optical communications on the other.

4. High Quality III-V Semiconductors/Si Heterostructures for Photonic Integration and Photovoltaic Applications
Sammanfattning : This thesis deals with one of the promising strategies to monolithically integrate III-V semiconductors with silicon via epitaxial lateral overgrowth (ELOG) technology and is supported by extensive experimental results. The aimed applications are light sources on silicon for electronics-photonics integration and cost effective high efficiency multijunction solar cells. LÄS MER
5. CVD solutions for new directions in SiC and GaN epitaxy
Sammanfattning : This thesis aims to develop a chemical vapor deposition (CVD) process for the new directions in both silicon carbon (SiC) and gallium nitride (GaN) epitaxial growth. The properties of the grown epitaxial layers are investigated in detail in order to have a deep understanding. LÄS MER
