摘要

Two-dimensional (2D) VIA group compounds, such as transition metal dichalcogenides (TMDs), ⅢA-ⅥA and ⅣA-ⅥA group compounds, as a new set of layered materials rising in recent years, have an obvious advantage over the extended studied monolayer graphene in optoelectronics due to their inherent bandgaps [1, 2].Similar as graphene, the initial fabrication of 2D ⅥA group compounds depends mainly on mechanical exfoliation method, although such a method is lack of control in morphology and yield of product.Based on the exfoliated samples, the optical, electronic, and optoelectronic properties of 2D materials have been systematically studied [1-3].Meanwhile, the efforts in exploration of new member of 2D materials are never ceased.
