Abstract

We propose a study to identify mono- and few-layers of molybdenum disulfide, molybdenum diselenide, tungsten disulfide, and tungsten diselenide. The number of layers is determined by optical microscopy. The single and few layers of the transition metal dichalcogenides transferred onto SiO2/Si substrates. SiO2/Si substrates with 270 nm
thickness SiO2 have been shown to provide high optical contrast, enabling optical
identification of the transition metal dichalcogenides easier.
