Mechanical exfoliation of MoS2 monolayer flakes — •Yuhao Zhang, Eicke Icking, and Stefan Linden — Physikalisches Institut, Nussallee 12, Universit at Bonn , 53115 Bonn, Germany

Transition metal dichalcogenide (TMDC) monolayers have attracted considerable interest in recent years. Here we report on the mechanical exfoliation and all-dry viscoelastic stamping [1] of MoS2 monolayer and few-layer flakes onto different substrates. The optical properties of these layers are characterized by differential reflectance and transmittance spectroscopy. Additional electron energy loss spectroscopy experiments are currently being carried out.
