Graphene: A New Paradigm in Condensed Matter and Device Physics is a complete description of the science and applications of graphene. Graphene, the single layer of graphite, is now recognized as a revolutionary two-dimensional one-atom-thick material of exceedingly high electrical conductivity and tensile strength. This book reviews the developments in physics and materials science, starting in 2004 that led to Nobel Prizes in Physics, for Andre Geim and Konstantin Novoselov in 2010. The physics is unusual, offering electrons in conical bands that behave more like photons or neutrinos and, as electrical carriers, remarkably free from backscattering. Nonetheless all of these aspects have been treated, as explained in this book, using the same methods that work well for silicon, the present basis of the information technology. The book describes graphene as the first in a new class of two-dimensional materials, effectively crystalline on practical size scales up to one meter. Graphene, despite theoretical predictions of non–crystallinity of two-dimensional matter at finite temperature, is actually refractory, estimated to exist nearly to 4,900K, well above the experimentally-known sublimation point of graphite at 3,900K. The key to potential applications of graphene lies in methods of fabrication that range from chemical exfoliation of graphite crystals to chemical vapor deposition methods similar to those of the present semiconductor industry. Applications expected in future generations of digital computing technology are described in this book. These include flash memory elements, on-chip interconnects, high frequency field-effect transistors and possible tunneling switching transistors fabricated from graphene.Less

The discovery of Novoselov, Geim et al. (2004, 2005) is of a new phase of two-dimensional matter, the prime example being graphene. This material is robust, an excellent conductor, refractory and extremely soft against bending. Its unique capability is excellent electrical conduction at one-atom thickness. Applications of inexpensive platelets of graphene are as conductive and flexible additives to composites and perhaps as electrodes of solar cells. Applications of high quality graphene grown on catalytic substrates and on SiC are potentially important in electronics. These include RF transistors, flash-memory cells, touch-screens and interconnects. A family of graphene FET transistors based on tunnelling is discussed as a potential successor to the CMOS family of logic devices in semiconductor electronics.Less
