Everyone is familiar with the amazing performance of a modern smartphone, powered by a billion-plus nanotransistors, each having an active region that is barely a few hundred atoms long. The same amazing technology has also led to a deeper understanding of the nature of current flow and heat dissipation on an atomic scale which is of broad relevance to the general problems of non-equilibrium statistical mechanics that pervade many different fields. This book is based on a set of two online courses originally offered in 2012 on nanoHUB-U and more recently in 2015 on edX. In preparing the second edition the author decided to split it into parts A and B titled Basic Concepts and Quantum Transport respectively, along the lines of the two courses. A list of available video lectures corresponding to different sections of this volume is provided upfront. To make these lectures accessible to anyone in any branch of science or engineering, the author assume very little background beyond linear algebra and differential equations. However, the author will be discussing advanced concepts that should be of interest even to specialists, who are encouraged to look at his earlier books for additional technical details. Key Features: o Based on a physically insightful approach that not only conveys the key concepts of nanoelectronics, but also their relevance to other non-equilibrium problems like heat flow, spin flow and entropy flow o The chapters are keyed to video lectures from the online courses offered on nanoHUB-U and on edX o The author received the 2008 IEEE Technical Field Award for graduate teaching "for his unique approach to quantum transport that has inspired and educated graduate students in the field of nanoscale electronic devices"
