Graphene-based transistors leverage the exceptional electron mobility of graphene, which allows electrons to move through the material with minimal resistance. This results in faster switching speeds and reduced power consumption. The basic structure of a graphene transistor typically includes a graphene channel, source and drain electrodes, and a gate electrode to control the current flow. However, the absence of an intrinsic bandgap in graphene can make it difficult to turn off the transistor completely, which is a significant challenge being actively researched.
