Emerging nanocircuit paradigm: Graphene-based electronics for nanoscale computing

The continued miniaturization of silicon-based electronic circuits is fast approaching the physical and geometrical limits over the past decades. It is unlikely that these advances in miniaturization can continue in the new millennium. Future nanoelectronics will go beyond the silicon technology. New circuit paradigms based on novel nanoscale materials, such as molecular electronic circuits and carbon-based circuits, will be employed. In this paper, we introduce an emerging nanocircuit paradigm, graphene nanoelectronics. Due to its unique quantum effects and electronic properties, researchers predict that graphene-based circuits will replace carbon nanotube circuits and become major building blocks for future nanoscale computing. To manifest its unique electronic properties, we present some of our recent designs, namely a switch, a field-effect transistor and a random access memory array (RAM). We also provide a common platform to simulate the circuit behavior and the platform can be used to design functional graphene-based computing system in future.
