Facile Synthesis of Single Crystal PtSe2 Nanosheets for Nanoscale Electronics

Ultrathin single crystal platinum diselenide (PtSe2) nanosheets are synthesized using H2PtCl6 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(2) 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.
