Abstract:A study has been made of the distribution of resistivity, concentration, and mobility of majority charge carriers, lifetime of minority charge carriers, and microhardness along Si wafer areas of more than 60 mm diameter grown in [lo01 direction doped wit,h As to 50 and 150 Rcm resistivity. Metallographic, X-ray, and electron microscopic investigations of both dislocation and dislocation-free ingots indicate high structural perfection. The influence is analysed of thermal treatment from 900 to 1300 "C on the st… 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.
