Optical properties of transition metal dichalcogenides under high pressure — •Paul Luca Großerhode, Paul Steeger, Robert Schmidt, Steffen Michaelis de Vasconcellos, and Rudolf Bratschitsch — Institute of Physics, University of Münster, Germany

Transition metal dichalcogenides (TMDCs), such as MoS₂ or WS₂, have received growing attention during the last years. Using micromechanical exfoliation, single semiconducting layers can be readily prepared. Furthermore, multi-layered artificial crystals can be fabricated with single layer precision. In this study, we use a diamond anvil cell to apply pressures in the gigapascal range on such samples and observe how their optical properties change due to the induced deformation.
