Prof. Joachim Knoch

University & Institute:
RWTH Aachen University, Institute of Semiconductor Electronics

Joachim Knoch studied physics at RWTH Aachen University and Queen Mary, University of London. He obtained the MSc and PhD degrees in physics from RWTH Aachen University in 1998 and 2001, respectively. From 2001 to 2002 he was a postdoctoral researcher at the Massachusetts Institute of Technology working on InP HEMTs.

Between 2003 and 2006 he was a research associate at Forschungszentrum Juelich, where where he investigated Schottky-barrier MOSFETs and Band-to-band Tunnel FETs. From 2006 to 2008 Joachim Knoch was a research staff member at IBM’s Zurich Research Laboratory working on nanowire field-effect transistors. In 2008 he was appointed associate professor at TU Dortmund University and continued to work on nanoscale field-effect transistor devices including 2D materials.

Since 2011 he has been full professor at RWTH Aachen University. His current research interest include the exploration of nanoelectronics devices for quantum information processing and neuromorphic systems based on different materials.
