Professor

overview

Dr. Stanchina's research interests include development of novel heterojunction electronic and optoelectronic devices and their application. During 21 years of industrial R&D, he conducted research in basic semiconductor materials growth through development of microelectronic devices and IC fabrication processes. He managed the transition of R&D through low volume production to supply high reliability, high performance components to government systems and commercial applications. At Pitt, he has established an electronic device measurement capability to characterize the physical structure of semiconductor devices and extract the equivalent circuit models necessary to utilize these devices in the design of components for applications. These devices are primarily wide bandgap and other compound semiconductor devices for application to smart grid power electronics and bio-medical instrumentation applications. Latest research is extending these semiconductors to nanowire growth and device development.
