Superior Gas Sensing Properties of Monolayer PtSe_2

摘要

2D materials have huge potential in future nanodevices, particularly transition metal dichalcogenides (TMDCs), which therefore are studied extensively in recent years.[1–5] TMDCs can have diverse electronic properties (metallic,[6] half-metallic,[7] semiconducting,[8] and superconducting[9]), depending on the number of transition metal d electrons and the structural polytype.[10] However, intrinsic limitations such as the relatively low carrier mobility in MoS_2 [8] call for further research. Monolayer PtSe_2 can provide an enhanced mobility and thus is of great interest for electronic applications.[11]
