Characterization of MoS<sub>2</sub> Flakes using Tip-Enhanced Optical Spectroscopies (TEOS)
28 Dec 2017Molybdenum disulfide (MoS2) is a promising semiconducting Transition Metal Dichalcogenide (TMD) 2D nano-material for next generation photovoltaic solar cells, optoelectronic circuits and sensors due to its great excitonic recombination property, high carrier mobility and low leakage current. One of the advantages of two dimensional (2D) TMDs, when compared to graphene, comes from quantum confinement, enabling the indirect-to-direct bandgap transition as a function of number of individual layers. Nano-scale characterization is needed for the understanding necessary to engineer nanodevices integrating monolayer MoS2.
