Highlights
•Nanoscale defects in III–V materials, grown over Si were characterized with CAFM.
•The defects exhibit higher conductivity.
•The contact rectifying feature is hide by a larger current under the reverse bias.
•Patterned samples fabricated using Aspect Ratio Trapping were also characterized.
Abstract
The implementation of high mobility devices requires [...]
Industrial diamond window blanks with optical transmissivity for IR-applications are commercially available. The applicable wavelengths of current diamond optical window components basically include all wavelengths from X-ray, deep ultraviolet to microwave. Therefore, there is a great significance for the development of optical windows/fairings used [...]
