ECE 495N Lecture 8: Shrödinger's Equation
0.0 out of 5 stars
30 Sep 2008 | Online Presentations | Contributor(s): Supriyo Datta
Quantum and Thermal Effects in Nanoscale Devices
4.5 out of 5 stars
18 Sep 2008 | Online Presentations | Contributor(s): Dragica Vasileska
To investigate lattice heating within a Monte Carlo device simulation framework, we simultaneously solve the Boltzmann transport equation for the electrons, the 2D Poisson equation to get the...
ECE 495N Lecture 7: Quantum Capacitance/Shrödinger's Equation
17 Sep 2008 | Online Presentations | Contributor(s): Supriyo Datta
Lecture 6: Quantum Transport in Nanoscale FETs
5.0 out of 5 stars
12 Sep 2008 | Online Presentations | Contributor(s): Mark Lundstrom
The previous lessons developed an analytical (or almost analytical) theory of the nanoscale FET, but to properly treat all the details, rigorous computer simulations are necessary. This lecture...
Lecture 4A: Energy Exchange and Maxwell's Demon
02 Sep 2008 | Online Presentations | Contributor(s): Supriyo Datta
Objective: To incorporate distributed energy exchange processes into the previous models from lectures 1 through 3 which are based on a "Landauer-like picture" where the Joule heating associated...
Introduction: Nanoelectronics and the meaning of resistance
4.0 out of 5 stars
20 Aug 2008 | Online Presentations | Contributor(s): Supriyo Datta
This lecture provides a brief overview of the five-day short course whose purpose is to introduce a unified viewpoint for a wide variety of nanoscale electronic devices of great interest for all...
Lecture 1A: What and where is the resistance?
Objective: To introduce a simple quantitative model that highlights the essential parameters that determine electrical conduction: the density of states in the channel, D and the rates at...
Lecture 1B: What and where is the resistance?
Lecture 2A: Quantum Transport
Objective: To extend the simple model from Lectures 1 into the full-fledged Non-equilibrium Green’s Function (NEGF) – Landauer model by introducing a spatial grid of N points and turning numbers...
Lecture 2B: Quantum Transport
Lecture 3A: Spin Transport
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...
Lecture 3B: Spin Transport
Lecture 4B: Energy Exchange and Maxwell’s Demon
Objective: To incorporate distributed energy exchange processes into the previous models from lectures 1 through 3 which are based on a “Landauer-like picture” where the Joule heating associated...
Lecture 5A: Correlations and Entanglement
Objective: To relate the one-electron picture used throughout these lectures to the more general but less tractable many-particle picture that underlies it. We introduce this new viewpoint using...
Lecture 5B: Correlations and Entanglement
Nano Carbon: From ballistic transistors to atomic drumheads
14 May 2008 | Online Presentations | Contributor(s): Paul L. McEuen
Carbon takes many forms, from precious diamonds to lowly graphite. Surprisingly, it is the latter that is the most prized by nano physicists. Graphene, a single layer of graphite, can serve as an...
Nanoelectronic Modeling: Multimillion Atom Simulations, Transport, and HPC Scaling to 23,000 Processors
07 Mar 2008 | Online Presentations | Contributor(s): Gerhard Klimeck
Future field effect transistors will be on the same length scales as “esoteric” devices such as quantum dots,
nanowires, ultra-scaled quantum wells, and resonant tunneling diodes. In those...
MCW07 A Quantum Open Systems Approach to Molecular-Scale Devices
25 Feb 2008 | Online Presentations | Contributor(s): Yongqiang Xue
Experimental advances in electrically and optically probing individual molecules have provided new insights into the behavior of single quantum objects and their interaction with the...
MCW07 Physics of Contact Induced Current Asymmetry in Transport Through Molecules
25 Feb 2008 | Online Presentations | Contributor(s): Bhaskaran Muralidharan, Owen D. Miller, Neeti Kapur, Avik Ghosh, Supriyo Datta
We first outline the qualitatively different physics involved in the charging-induced current asymmetries in molecular conductors operating in the strongly coupled (weakly interacting)...
Exploring Physical and Chemical control of molecular conductance: A computational study
