The advances in communications technology depend on the development of tiny devices being capable of transmitting and receiving data at the highest possible data rates. The digital signal processing at gigabit-per-second rates is soon to be upgraded to the terabit-per-second range. Nanotechnology provides a variety of alternatives for the design of ultrafast nanoscale components. Graphene is one particular material which is considered for possible implementation due to its superior physical properties. This contribution is based on a selection of some foundation studies which explore the potential of graphene for emerging applications with an emphasis on communications technology
