Abstract:Due to their extended electronic structure shallow donors are believed to be very sensitive to confinement effects. Our interest is to investigate the influence of size on the properties of shallow donor phosphorus in mechanically milled silicon microcrystals. The crystallinity of powders is confirmed by X-ray diffraction and the size as determined by scanning electron microscopy was found to be 0.25 mm for smallest to 4 mm for largest microcrystals. In the current experiment we use electron paramagnetic reson… Show more
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.
