Lessons from Nanoelectronics (LNE)
* LNE is intended for a broad audience including students and professionals in other science and engineering disciplines. It assumes a knowledge of differential equations and linear algebra, but no specific disciplinary background.
The last part of this book devoted to making the NEGF (NonEquilibrium Green’s Function) method accessible to to all science and engineering students (with concrete examples and appropriate caveats) without requiring a background in advanced quantum statistical mechanics.
Note
In the Second Edition (2017) the book was reorganized to correspond more closely to the two online courses. The 2017 Edition also split the book into Part A (Chapters 116) and Part B (Chapters 1725).
These Q&A were written in 2013 based on the First Edition (2012).
Here are the corresponding chapters in the 2017 Edition (2012 Edition):
Part A: 14 (14), 5 (15), 6 (5), 7 (8), 89 (67), 10 (12 and 14), 11 (13), 12 (9), 1314 (1011), 1516 (1617).
Part B : 1720 (1821), 22 (23), 23 (22), 24 (24).
Chapters 21 and 25 of 2017 Edition are new.

Online Course
This book (LNE) was developed as an accompanying text for an online course first offered on nanoHUB in 2012, and later on edX in 2015 and 2018. Related video lectures, quizzes, homework problems and solutions can all be accessed by going to
Selfpaced course on Fundamentals of Nanoelectronics, Part I: Basic Concepts
Selfpaced course on Fundamentals of Nanoelectronics, Part II: Quantum Models

What the book is about
Everyone is familiar with the amazing performance of a modern smartphone, powered by a billionplus nanotransistors, each having an active region that is barely a few hundred atoms long.
These lectures, however, are about a lessappreciated byproduct of the microelectronics revolution, namely the deeper understanding of current flow, energy exchange and device operation that it has enabled. We
* (1) introduce the seminal concepts of nanoelectronics and mesoscopic physics, and
* (2) show how these concepts can be used to obtain many standard results in the transport theory of large conductors in a relatively straightforward way.
This second point represents a new perspective that could be of broad relevance to the general problems of nonequilibrium statistical mechanics involving the emergence of irreversibility from reversible laws. With this in mind we have tried to make the key concepts accessible to a broad audience.
Over 50 years ago David Pines in his preface to the Frontiers in Physics lecture note series articulated the need for both a consistent account of a field and the presentation of a definite point of view concerning it. That is what we have tried to provide in this book, with no intent to slight any other point of view or perspective.
Intended audience
Students and professionals in any branch of science or engineering. We assume very little background beyond linear algebra and differential equations.
For dedicated graduate students and the specialists, I have written a number of BOOKS in the past.
But even the specialists may enjoy these notes taking a fresh look at a familiar subject, emphasizing the insights from mesoscopic physics and nanoelectronics that are of general interest and relevance.

MATLAB codes
These codes can be run on MATLAB or on the OCTAViEw tool on nanoHUB.
