1. 1. 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

3. 2. Magnetron sputter epitaxy of 2h-Al1-xInxN thin films

   Författare :Timo Seppänen; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis describes the growth and structural characterization of epitaxial 2h­ A11-xInxN ranging from pure A1N to InN [01-xInxN films were synthesized by dual DC reactive Magnetron Sputter Epitaxy (MSE) in an ultra-high vacuum (UHV) system. Growth parameters such as deposition temperature and magnetron power settings were adjusted in order to control the film stoichiometry. LÄS MER
