Dr. Stefan Weber
Feodor Lynen Research Fellow
Stefan Weber studied physics at the University of Konstanz (Germany) and received his diploma in 2007. In his diploma thesis, he investigated the interaction of gold nanoparticles under pulsed laser irradiation. From 2007 to 2010 he did his PhD in the group of Prof. Hans-Jürgen Butt at the MPI for Polymer Research in Mainz, Germany. He used electrical SPM modes such as conductive scanning force microcopy and Kelvin probe force microscopy for the investigation of organic optoelectronic materials such as polymer solarcells. Within the Korean-German International Research Training Group (IRTG) ‘‘Self-Organized Materials for Optoelectronics’’ he spent six months of his PhD at Seoul National University (SNU) in Korea and received a joint degree from SNU and Mainz University. In August 2011 he joined the Nanoscale Function Group with a Feodor Lynen scholarship from the Alexander von Humboldt foundation.
Current Research Interests
The development and fundamental understanding of methods for liquid environment Kelvin probe force microscopy.
