Lisa Porter received the Ph.D. and B.S. degrees in Materials Science & Engineering from N.C. State University and Cornell University, respectively. She serves as a research and academic advisor to both graduate and undergraduate students and is actively involved in several outreach activities and societies. In 2011 she will serve as Program Chair of the Electronic Materials & Processing Division of the American Vacuum Society. Her awards include the “Women Driving the Material World” Award from the Women & Girls Foundation of Southwest Pennsylvania (2006), a National Science Foundation Career Award (1999-2004) and a National Swedish Foundation Visiting Professorship (2000-2002).
Professor Porter's research activities are focused on the analysis of chemistry, microstructure, and electrical properties of electronically-functional interfaces. We are interested in a range of materials including but not limited to wide band-gap semiconductors; dielectric-semiconductor interfaces, as for example in metal-oxide-semiconductor (MOS) devices; polymer organic semiconductors and thin films. We are also interested in a range of applications and devices, including chemical and gas sensors, field-effect transistors (FETs), Schottky diodes, light-emitting diodes and solar cells. Examples of current research projects include the improving ohmic contacts for high-efficiency nitride-based LEDs; investigating the relationship between morphology, mobility and contact resistance in organic FETs, and the developing thermally-stable interfaces for solid-state semiconductor gas sensors.
