Theory of Electron Transport in Semiconductors : A Pathway from Elementary Physics to Nonequilibrium Green Functions This book describes in details the theory of the electron transport in the materials and structures at the basis of modern micro and nano electronics. It leads and accompanies the reader through a step by step derivation of all calculations from the basic laws of classical and quantum physics up to the most modern theoretical techniques such as nonequilibrium Green functions to study transport properties of both semiconductor materials and modern low dimensional and mesoscopic structures. This book covers electron transport in the materials and structures at the basis of micro and nano electronics. It offers step by step derivation of all calculations from basic laws of classical and quantum physics to modern theoretical technique
