Over the years our group has worked in many different areas, the dominant theme being current flow (that is, electronic transport) in nanostructures, including Spin Electronics, Nanoscale Device Physics, Mesoscopic Physics and Mesoscopic Superconductivity, Molecular Electronics.
Our primary research interest at this time is centered around
** Spin Transistor, Spin Circuits and Spin Logic, and
** the theroretical framework used for their analysis and design.
Our first paper on this topic published in 1989,
established the relation between the NEGF method of many-body physics and the Landauer approach of mesoscopic physics.
Since then a significant part of our group’s research has been focused on developing what we call the NEGF-Landauer method into a suitable conceptual framework for the description of quantum transport. This approach is now widely used in the modeling of quantum transport in nanoscale electronic devices.
My books are an extension of our group research, seeking to convey research results like the NEGF method to graduate students, professionals and more recently to a broader audience.
* Quantum Transport: Atom to Transistor, Cambridge 2005 is intended to introduce the NEGF method to graduate students in electrical engineering, physics and chemistry. * Chapters 8-11 and the Appendix present the NEGF method.
* Electronic Transport in Mesoscopic Systems, Cambridge 1995, 1997 is intended to introduce the scattering theory of transport (Landauer-Buttiker formalism) and relate it to the NEGF method, with graduate students in physics and electrical engineering in mind. * Chapter 8 presents the NEGF method relating it to the Landauer formalism.
* LNE: Lessons from Nanoelectronics, World Scientific 2012 is intended for a broad audience including students and professionals in other science and engineering disciplines. ** Part III (Lectures 18-23) of this book is devoted to making the NEGF (Non-Equilibrium Green’s Function) method accessible to non-specialists.
* (1) introduces the seminal concepts of nanoelectronics and mesoscopic physics, and
* (2) shows that these concepts are not only relevant to small conductors but can also be used to obtain many standard results in the transport theory of large conductors in a relatively straightforward way.
This second point represents the new perspective and both (1) and (2) could be of broad relevance to the general problems of non-equilibrium 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.
In Spring 2012 an online course on the Fundamentals of Nanoelectronics was offered using LNE as the text. Related video lectures, quizzes, homework problems and solutions can all be accessed by going to
