Most recently, PVD and CVD have been employed to prepare
single layer In2Se3.16 PVD has been used successfully to prepare
GaSe and lateral heterojunctions.22−24 Lin et al. epitaxially
synthesized In2Se3 layers on mica and graphene.16 Monolayered
In2Se3 were obtained along with the formation of thick In2Se3
layers. This method opened a new way to synthesize the largesize
In2Se3 monolayer.
