Two-dimensional (2D) molybdenum trioxide has been attracting research interest due to its bandgap tunability and a wide variety of desirable electronic/optoelectronic properties. However, the lack of a reproducible synthesis process for obtaining large coverage 2D MoO has limited the use of this material. Here we report the synthesis of large area 2D MoO via physical vapor deposition, using MoO powder as the precursor. The as-grown layers are directly deposited on SiO /Si, eliminating the necessity for any transfer process. These as-grown MoO layers allow for the large-scale fabrication of planar device arrays. The applicability of 2D MoO in optoelectronics is established via the demons..
