Regensburg physicists around Dr. Tobias Korn, Institute for Experimental and Applied Physics of the University of Regensburg, have investigated atomically thin heterostructures of the two-dimensional materials molybdenum disulfide (MoS2) and tungsten diselenide (WSe2) in an international collaboration with researchers from the TU Dresden and Columbia University in New York. They found out that the charge carriers (electrons and holes) in such a structure do not completely separate from each other, as previously thought, but are partly in both materials at the same time. This is an important finding, as well for basic research as for technological applications. The results were published in the journal "Nature Physics".
