P.M. Lenahan

P.M. Lenahan earned his B.S. degree from the University of Notre Dame and his Ph.D. from the University of Illinois, Champaign-Urbana. After completing his Ph.D. in 1979, he was a post-doctoral fellow at Princeton University in 1979 and 1980. From 1980 until 1985 he was a member of the technical staff in the Materials Research Directorate of Sandia National Laboratories in Albuquerque, New Mexico. Since 1985 he has been at Penn State University where he is Professor of Engineering Science and Mechanics (ESM). ESM is the materials engineering and applied physics department of the Penn State Engineering College; the department also operates an honors degree program for engineering students interested in applied physics. In 2001, he was visiting professor of Electronics and Computer Engineering at Nihon University, Tokyo, Japan (Nihon University is the largest university in Japan). From 2000 through 2004 he served as an associate editor of the Journal of Electronic Materials.

Patrick Lenahan has authored over 150 publications (approximately 120 in refereed journals and 30 in refereed conference proceedings volumes. 150 conference presentations, and one patent. The publications have been cited approximately 2900 times. His research has been primarily focused upon the trapping centers in semiconductors and insulators: amorphous SiO₂, nitrogen, phosphorous, and boron “doped” SiO₂, silicon nitrides, silicon oxynitrides, Si/SiO₂ interfaces, silicon grain boundaries and silicon carbide with a variety of electrical measurements and electron spin resonance techniques.

In 2006, P. Lenahan serves on organized committees of:

The Electronic Materials Conference
The IEEE International Integrated Reliability Workshop
The IEEE International Electronic Devices Meeting
The IEEE Semiconductor-Interface Specialty
The Electron Paramagnetic Resonance Symposium of the Rocky
Mountain Conference of Analytical Chemistry

Students Currently Working In the Lab

Jason Campbell - Jason P. Campbell received his B.S. in Engineering Science from Penn State University in 2001. He is currently pursuing his Ph.D in Engineering Science from Penn State University. His current research involves the atomic scale mechanisms responsible for NBTI.
	Morgen Dautrich - Morgen received his B.S. in Electrical Engineering in 2003 and his M.S. in Engineering Science in 2006, both from Penn State. He is currently working on a collaborative project between PSU and Army Research Lab to investigate defects in silicon carbide-based MOSFETs.
Jason Ryan - Jason Ryan completed his M.S. in Engineering Science at Penn State in May 2006. He is currently pursuing a Ph.D. in Materials Science and Engineering.
	Corey Cochrane - Corey is pursuing his Master's degree in Electrical Engineering with an emphasis in digital signal processing. His research interests include adaptive and intelligent filter/network design to improve the sensitivity of the SDR technique. Corey is also investigating defects within silicon carbide bipolar junction transistors and Hafnium Oxide (high K) based MOSFETS.
Aaron Rape - Aaron is beginning his studies working towards a Ph.D. in Materials Science in the summer of 2006. He is interested in improving semiconductor devices as well as using magnetic resonance as a way of detecting enriched uranium.
	Ted Macdonald - Ted is an undergraduate Electrical Engineering major and plans to graduate in the spring of 2007. He is interested in robotics.
