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