Lecture 3A: Spin Transport
Online Presentations | 20 Aug 2008 | Contributor(s):: Supriyo Datta
Objective: To extend the model from Lectures 1 and 2 to include electron spin. Every electron is an elementary “magnet” with two states having opposite magnetic moments. Usually this has no major effect on device operation except to increase the conductance by a factor of two.But it is now...

Silicon Spintronics
Online Presentations | 04 Jun 2008 | Contributor(s):: Ian Appelbaum
"Electronics" uses our ability to control electrons with electric fields via interaction with their fundamental charge. Because we can manipulate the electric fields within semiconductors, they are the basis for microelectronics, and silicon (Si) is the most widely-used semiconductor for...

The Novel Nanostructures of Carbon
Online Presentations | 28 Feb 2008 | Contributor(s):: Gene Dresselhaus
A brief review will be given of the physical underpinnings of carbon nanostructures that were developed over the past 60 years, starting with the electronic structure and physical properties of graphene and graphite, and then moving to graphite intercalation compounds which contained the first...

Surprises on the nanoscale: Plasmonic waves that travel backward and spin birefringence without magnetic fields
Online Presentations | 08 Jan 2007 | Contributor(s):: Daniel Neuhauser
As nanonphotonics and nanoelectronics are pushed down towards the molecular scale, interesting effects emerge. We discuss how birefringence (different propagation of two polarizations) is manifested and could be useful in the future for two systems: coherent plasmonic transport of near-field...

A MATLAB code for Hartree Fock calculation of H-H ground state bondlength and energy using STO-4G
Downloads | 08 Aug 2006 | Contributor(s):: Amritanshu Palaria
Hartree Fock (HF) theory is one of the basic theories underlying the current understanding of the electronic structure of materials. It is a simple non-relativistic treatment of many electron system that accounts for the antisymmetric (fermion) nature of electronic wavefunction but does not...

Control of Exchange Interaction in a Double Dot System
Online Presentations | 05 Feb 2004 | Contributor(s):: Mike Stopa
As Rolf Landauer observed in 1960, information is physical. As a consequence, the transport and processing of information must obey the laws of physics. It therefore makes sense to base the laws of information processing and computation on the laws of physics and in particular on quantum...

Spin Valve Spin-Circuit Model
Downloads | 26 Oct 2014 | Contributor(s):: Kerem Yunus Camsari, Samiran Ganguly
Spin Valves were the first spintronic devices to have been made. They are composed of two magnets spearated by a non-magnetic metallic spacer. The resistance of this device depends on the relative angle betwwent he magnetization direction of the two magnets. These devices have been used...
