Dr. Christoph Kastl
Academic Career and Research Areas
The research group of Dr. Christoph Kastl (*1986) investigates the fundamental optical and electronic properties of low-dimensional materials towards their application in semiconductor and quantum technologies. His recent ERC starting grant project explores low-dimensional solid-state systems with tailored electronic properties and topology. To this end, he makes use of novel periodic superlattices in two-dimensional heterostructures, which are fabricated using state-of-the-art, top-down nanofabrication with a resolution of few nanometers.
Dr. Christoph Kastl studied physics and was awarded a doctoral degree in experimental solid-state physics at TUM in 2015. His doctoral research focused on fundamental studies of non-trivial, topological surface state in novel semiconductors. As a post-doc (2015-2019) at the Molecular Foundry (Lawrence Berkeley National Laboratory), he studied the optoelectronic defect properties of two-dimensional semiconductors. Since 2019, he heads a junior research group at Walter-Schottky-Institute of TUM.
