Abstract
A photodetector includes a substrate, a graphene layer disposed on the substrate, a first electrode disposed on the graphene layer, and a second electrode disposed on the graphene layer, where the first and second electrodes are spaced apart from each other, and where each of the first and second electrodes comprises a complex transparent electrode. The complex transparent electrode of the first electrode may have a different composition from the complex transparent electrode of the second electrode.
