Abstract
In the increasing research field of 2D materials such graphene, Molybdenum disulfide MoS2 attracted a great interest due to potential applications as thin film transistors, light-emitting diodes or or photodetectors. Differently than graphene, the existence of a direct bandgap in monolayer MoS2, gives the possibility of performing MoS2 field-effect transistors or optoelectronic devices. We analyzed by THz-Time Domain Spectroscopy (THz-TDS) of CVD obtained MoS2 deposited on a sapphire substrate. The advantage of THz-TDS method is that we can get significant parameters related to the sample quality like conductivity, permittivity or attenuation, without the need of depositing any electrical contacts or sample preparation.
