Multidimensional nanoscale device modeling: the finite element method applied to the nonequilibrium Green's function formalism
31 Oct 2006   Contributor(s):: POLIZZI ERIC, Supriyo Datta
This work deals with the modeling and the numerical simulation of quantum transport in multidimensional open nanoscale devices. The electron transport in the device is described using the NonEquilibrium Green's Functions (NEGF) formalism and the variational form of the problem is solved using...

Non Equilibrium Green's Functions for Dummies: Introduction to the One Particle NEGF equations
30 Oct 2006   Contributor(s):: Magnus Paulsson
Non equilibrium Green's function methods are regularly used to calculate current and charge densities in nanoscale (both molecular and semiconductor) conductors under bias. This method is mainly used for ballistic conduction but may be extended to include inelastic scattering. In this tutorial...

Why is Nanotechnology Multidisciplinary? A perspective of one EE
19 Oct 2006   Contributor(s):: Gerhard Klimeck
The field of nano science and nanotechnology covers broad areas of expertise. Classical fields of Physics, Chemistry, Material Science, Electrical/Mechanical/Chemical Engineering all are involved in the "new" field. Nano research and development is therefore multidisciplinary. This presentation...

Modeling Quantum Transport in Nanoscale Transistors
30 Oct 2006   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   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 highκ gate...

Electrical Resistance: an Atomistic View
26 Oct 2006   Contributor(s):: Supriyo Datta
This tutorial article presents a “bottomup” view of electrical resistance starting from something really small, like a molecule, and then discussing the issues that arise as we move to bigger conductors. Remark ably enough, no serious quantum mechanics is needed to understand electrical...
