Abstract

Ultrathin single crystal platinum diselenide (PtSe₂ ) nanosheets are synthesized using H₂ PtCl₆ and Se as the precursors. The electronic properties are first investigated and exhibit p-type transport behavior with the mobility much larger than 7 cm² V^-1 s^-1 . The further investigation on PtSe₂ /MoS₂ var der Waals p-n junction demonstrated that PtSe₂ could be potentially applied in 2D electronics.

Keywords: 2D materials; Raman spectroscopy; molybdenum disulfide; platinum diselenide; transition metal dichalcogenides.
