Abstract:Base current reversal phenomenon is newly observed in a CMOS compatible high gain n-p-n gated lateral bipolar transistor. We attribute this phenomenon to avalanche generation as verified experimentally and by two-dimensional device simulation. Detailed investigation reveals that: i) the multiplication ratio increases exponentially with the collector voltage or equivalently the peak field at the surface collector corner; and ii) the multiplication ratio is independent of not only the low level base-emitter forw… 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.
