(a) Top view of the sample and the transistor geometry with labels projected onto a microscope image of one device. For clarity, the SiO2 region not covered by graphene is highlighted by a solid black line and the gate is highlighted by a dotted line. (b) Schematic three-dimensional representation of a fabricated graphene transistor comprising of the substrate layers, its contact pads and the illuminated graphene gate with a light-absorbing cQDs layer deposited on top of it.
