Abstract

Ultrathin single crystal platinum diselenide (PtSe<sub>2</sub> ) nanosheets are synthesized using H<sub>2</sub> PtCl<sub>6</sub> and Se as the precursors. The electronic properties are first investigated and exhibit p-type transport behavior with the mobility much larger than 7 cm<sup>2</sup> V<sup>-1</sup> s<sup>-1</sup> . The further investigation on PtSe<sub>2</sub> /MoS<sub>2</sub> var der Waals p-n junction demonstrated that PtSe<sub>2</sub> could be potentially applied in 2D electronics.
