(a) Cross-sectional illustration of introduced strain by the pressure difference in the device structure for DEVICE 1. Scanning electron micrographs of the hole fabricated in the substrate (b) before and (c) after graphene transfer. Bars represent 5Â ÎĽm. (d) Typical Raman spectrum of graphene used for DEVICE 1, showing multilayer graphene with negligible defects.
