Overview

  • Karsten Pohl completed his doctorate in surface physics with Prof. E. Ward Plummer, by studying the electronic and geometric surface structure of hydrogen adsorption on beryllium surfaces with a combination of photoelectron spectroscopies and low-energy electron diffraction. After working with Drs. Robert Hwang and Norman Bartelt at Sandia National Laboratories in California on strain effects in ultrathin film self-assembly on metal surfaces as a post-doctoral fellow, developing a novel scanning tunneling microscope in the process, he joined the Faculty of the University of New Hampshire in 2000, where he is a Professor in the Department of Physics and the Materials Science Program. His group explores molecular and stress relaxation driven self-assembly processes yielding novel nano-materials and the electronic properties of reduced dimensional systems, involving experimental tools such as scanning probe microscopy, photoelectron spectroscopy, and low-energy electron microscopy or LEEM, as well as extensive numerical modeling. Dr. Pohl is a founding member of the NSF-Center for High-rate Nanomanufacturing at UNH and has received an Early Career Award from the National Science Foundation in 2002. He was a Visiting Professor at the University of Genua, Italy in 2007.
