1. 1. Chemical Vapour Deposition of sp2 Hybridised Boron Nitride

   Författare :Mikhail Chubarov; Anne Henry; Henrik Pedersen; Hans Högberg; Robert F. Davis; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The aim of this work was to develop a chemical vapour deposition process and understand the growth of sp2 hybridised Boron Nitride (sp2-BN). Thus, the growth on different substrates together with the variation of growth parameters was investigated in details and is presented in the papers included in this thesis. LÄS MER

3. 2. Growth and Characterization of Metastable Wide Band-Gap Al1-xInxN Epilayers

   Författare :Timo Seppänen; Robert F. Davis; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin film; Magnetron Sputter Epitaxy MSE ; Physics; Fysik;

   Sammanfattning : InN to 6.2 eV for AlN, which opens possibilities to engineer opto-electronic devices operating from infra-red to deep ultra-violet wavelengths. Al1-xInxN with the alloy composition x~0.2 can also be used as a lattice-matched electron confinement layer for GaN based electronic devices. LÄS MER

4. 3. High growth rate epitaxy of SiC: growth processes and structural quality

   Författare :Mikael Syväjärvi; Robert F. Davis; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Silicon carbide (SiC) is a promising wide-bandgap semiconductor for applications such as high-power devices, high-voltage switches, high-temperature electronics and microwave components. The prospect of using this material is a large driving force for improving the material growth which is still quite immature in comparison with established semiconductor materials (e. LÄS MER
