Modeling Quantum Transport in Nanoscale Transistors

30 Oct 2006 | Publications | Contributor(s): Ramesh Venugopal

As critical transistor dimensions scale below the 100 nm (nanoscale) regime, quan- tum mechanical effects begin to manifest themselves and affect important device performance metrics. Therefore, simulation tools which can be applied to design nanoscale transistors in the future, require new …

Carbon Nanotube Electronics: Modeling, Physics, and Applications

30 Oct 2006 | Publications | Contributor(s): Jing Guo

In recent years, significant progress in understanding the physics of carbon nanotube electronic devices and in identifying potential applications has occurred. In a nanotube, low bias transport can be nearly ballistic across distances of several hundred nanometers. Deposition of high-κ …

Introduction to the Keldysh Nonequilibrium Green Function Technique

06 Oct 2006 | Publications | Contributor(s): A. P. Jauho

Keldysh nonequilibrium Green function technique is used very widely to describe transport phenomena in mesoscopic systems. The technique is somewhat subtle, and a rigorous treatment would require much more than we have at our disposal, see, for example, the text-bookk by Haug and Jauho [1]. The …

Towards Multi-Scale Modeling of Carbon Nanotube Transistors

20 Sep 2006 | Publications | Contributor(s): Jing Guo, Supriyo Datta, Mark Lundstrom, M. P. Anantram

Multiscale simulation approaches are needed in order to address scientific and technological questions in the rapidly developing field of carbon nanotube electronics. In this paper, we describe an effort underway to develop a comprehensive capability for multiscale simulation of carbon …

Nanoscale Device Modeling: From MOSFETs to Molecules

20 Sep 2006 | Publications | Contributor(s): Prashant Subhash Damle

This thesis presents a rigorous yet practical approach to model quantum transport in nanoscale electronic devices. As convetional metal oxide semiconductor devices shrink below the one hundred nanometer regime, quantum mechanical effects are beginning to play an increasingly important role in …

Quantum Transport for Nanostructures

17 Sep 2006 | Publications | Contributor(s): Mathieu Luisier

Nonequilibrium Green's function techniques, initiated by Schwinger and Kadanoff and Baym allow ones to study the time evolution of a many-particle quantum sys- tem. Knowing the 1-particle Green's functions of a given system, one may evaluate 1-particle quantities like carrier density or …
