Microfluidics is a viable route to making graphene-based opto-electronics, claims the University of Exeter. The aim is to exploit flakes of graphene and other 2D materials suspended in microfluidic structures which can be coupled to CMOS photonic circuits. The fluids in the micro-channels are liquid crystals, which can be controlled to physically hold optically-active graphene …
