Shaloo Rakheja: The Role of Graphene in Semiconductor Technologies

With its rich physical properties, the novel 2-D carbon-based material graphene is expected to play an important role in the advancement of semiconductor technologies. In a recent poll conducted by the International Technology Roadmap for Semiconductors (ITRS), graphene is named as the material most likely to have the greatest impact on geometric scaling. As a two-dimensional material, graphene has a limited phase space for scattering of electrons; hence, the electrons in graphene can have a long mean free path – a property that can be utilized to build a variety of high frequency analog devices and to implement low-power on-chip interconnects. Further, the ambipolar characteristics of graphene allow frequency doubler circuits implemented with a single transistor – something that is not possible with silicon transistors.
