Nanotechnology: Lighting up ultrathin films

Posted by in categories: nanotechnology, physics

Based on a study of the optical properties of novel ultrathin semiconductors, researchers of Ludwig-Maximilians-Universität München (LMU) in Munich have developed a method for rapid and efficient characterization of these materials.

Chemical compounds based on elements that belong to the so-called transition metals can be processed to yield atomically thin two-dimensional crystals consisting of a monolayer of the composite in question. The resulting materials are semiconductors with surprising optical properties. In cooperation with American colleagues, a team of LMU physicists led by Alexander Högele has now explored the properties of thin-film semiconductors made up of transition metal dichalcogenides (TMDs).

The researchers report their findings in the journal Nature Nanotechnology (“Opto-valleytronic imaging of atomically thin semiconductors”).
