Facile Synthesis of Single Crystal PtSe2 Nanosheets for Nanoscale Electronics

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.
