Solvents play a key part in synthesis, transfer, and device fabrication of two-dimensional (2D) materials. In article number 1600241, Yang Xu, Tawfique Hasan, and co-workers demonstrate solvent assisted soft-patterning of graphene heterostructures for high-performance photo detection. The solvent patterned graphene/Si Schottky photo detectors work in a broadband range with high speed, outperforming most of the previously reported devices.
