Abstract : This grant was used to support the research work of a graduate student (Byong Kim) on this project which was for us to improve the understanding of internal photoemission for Schottky-barrier IR detectors (SBIRDs) and to attempt to use this improved understanding to design either more efficient SBIRDs or SBIRDs with improved wavelength of operation or to increase the operating temperature. We used the newly developed technique of ballistic electron emission microscopy to carry out this work.
