Advanced Physics of Electron Transport in Semiconductors and Nanostructures

by Massimo V. Fischetti, William G. Vandenberghe

2016 · Springer

This textbook is aimed at second-year graduate students in Physics, Electrical Engineering, or Materials Science. It presents a rigorous introduction to electronic transport in solids, especially at the nanometer scale.Understanding electronic transport in solids requires some basic knowledge of Hamiltonian Classical Mechanics, Quantum Mechanics, Condensed Matter Theory, and Statistical Mechanics. Hence, this book discusses those sub-topics which are required to deal with electronic transport in a single, self-contained course. This will be useful for students who intend to work in academia or the nano/ micro-electronics industry.Further topics covered include: the theory of energy bands in crystals, of second quantization and elementary excitations in solids, of the dielectric properties of semiconductors with an emphasis on dielectric screening and coupled interfacial modes, of electron scattering with phonons, plasmons, electrons and photons, of the derivation of transport equations in semiconductors and semiconductor nanostructures somewhat at the quantum level, but mainly at the semi-classical level. The text presents examples relevant to current research, thus not only about Si, but also about III-V compound semiconductors, nanowires, graphene and graphene nanoribbons. In particular, the text gives major emphasis to plane-wave methods applied to the electronic structure of solids, both DFT and empirical pseudopotentials, always paying attention to their effects on electronic transport and its numerical treatment. The core of the text is electronic transport, with ample discussions of the transport equations derived both in the quantum picture (the Liouville-von Neumann equation) and semi-classically (the Boltzmann transport equation, BTE). An advanced chapter, Chapter 18, is strictly related to the ‘tricky’ transition from the time-reversible Liouville-von Neumann equation to the time-irreversible Green’s functions, to the density-matrix formalism and, classically, to the Boltzmann transport equation. Finally, several methods for solving the BTE are also reviewed, including the method of moments, iterative methods, direct matrix inversion, Cellular Automata and Monte Carlo. Four appendices complete the text.

Welch

by William R. Archer

2006 · Arcadia Publishing

After the Civil War, Capt. Isaiah Welch, a Doddridge County, West Virginia, native, took a job as a surveyor with Maj. Jed Hotchkiss of Staunton, Virginia. Hotchkiss had served as Gen. Thomas "Stonewall" Jackson's mapmaker and charted Jackson's famous Valley Campaign, and Welch had been an officer of the 13th Battalion, Virginia Light Artillery. The war left Virginia's agrarian economy in ruins, and men like Hotchkiss and Welch worked to develop a new, industrial South. Welch surveyed the Pocahontas Coalfield in 1873, and a city named in his honor emerged in the heart of that great coalfield. Chartered on July 12, 1894, Welch has played a pivotal role in America's industrial revolution as a support system and supply house to the timber industry and as a coal industry hub. Throughout more than a century, Welch has served as a gateway for the raw materials and manpower that fueled the nation's quest for growth and power. The city has been constantly beset by the challenges of maintaining a civilization in West Virginia's steepest and most remote mountains, but after decades of being tested by nature, Welch is now on the verge of yet another renaissance.
