Solar Blind Ultraviolet (SBUV) communication techniques have promise to address the military's needs for short range applications where non4ine-ofsight (NLOS) and a low probability of interception and detection (LPI/LPD) is required. This paper will address the general requirements for these systems and will discuss an example system developed using a compact quadrupled Nd:YAG laser.
An automated system for dark conductivity and Hall measurements and photoconductivity and photo-Hall characterization of high resistivity semiconductors is described. This system has been applied to commercially available semi-insulating GaAs substrates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
