Heayoung Yoon

Heayoung Yoon is a CNST/UMD Postdoctoral Researcher in the Energy Research Group. She received her B. S. and M. S. in Physics in Korea from Chungnam National University and Pohang University of Science and Technology, respectively.  Following two years as a researcher at the Samsung Advanced Institute of Technology, Heayoung entered graduate school at The Pennsylvania State University. She received a Ph. D. in Electrical Engineering at Penn State, where her research focused on micro/nanofabrication and electrical/spectroscopic characterization of self-assembled monolayer molecular junctions. She continued postdoctoral research at Penn State on molecular electronic devices, radiosensitive RF detectors, and high-aspect-ratio pillar array solar cells. In the CNST, Heayoung is working with Nikolai Zhitenev developing measurements of local electronic and optical properties of solar materials patterned into nanoscale devices.
