Graphene a two-dimensional, single atomic layer material with linear electron dispersion has rather unique electrical and properties1. There is currently strong interest in taking advantage of these properties for technological applications2. In my talk I will review some of the key properties of graphene, how these are affected by environmental interactions and how they can be utilized in electronics and optoelectronics.
Specifically, I will discuss high frequency (>100 GHz) graphene transistors3,4, their fabrication and operation, as well as related device physics aspects, such as carrier transport mechanisms, electrical contacts, temperature effects, energy dissipation, etc. Simple integrated graphene circuits will also be presented. I will then discuss key optical properties of graphene and how they can be combined with its excellent electrical properties and used in optoelectronics applications. Specific examples involving ultrafast graphene photodetectors5 and their applications in the detection of optical data streams6 will be presented.
