MCW07 Modeling MoleculeAssisted Transport in Nanotransistors
06 Nov 2007   Contributor(s):: Kamil Walczak
Molecular electronics faces many problems in practical device implementation, due to difficulties with fabrication and gateability. In these devices, molecules act as the main conducting channel. One could imagine alternate device structures where molecules act as quantum dots rather than...

MCW07 Simple Models for Molecular Transport Junctions
13 Sep 2007   Contributor(s):: , Abraham Nitzan, Mark Ratner
We review our recent research on role of interactions in molecular transport junctions. We consider simple models within nonequilibrium Green function approach (NEGF) in steadystate regime.

MCW07 Modeling Chargingbased Switching in Molecular Transport Junctions
23 Aug 2007   Contributor(s):: Sina Yeganeh, , Mark Ratner
We will discuss several proposed explanations for the switching and negative differential resistance behavior seen in some molecular junctions. It is shown that a proposed polaron model is successful in predicting both hysteresis and NDR behavior, and the model is elaborated with image charge...

Introduction to FETToy
03 Jul 2007   Contributor(s):: James K Fodor, Jing Guo
This learning module introduces nanoHUB users to the FETToy simulator. A brief introduction to FETToy is presented, followed by voiced presentations featuring the simulator in action. Upon completion of this module, users should be able to use this simulator to gain valuable insight into the...

NEGF Formulism Question
Open  Responses: 1
Hi,
I’m not too familiar with the NEGF formalism. But had a very basic question.
I’ve read that NEGF can be viewed as a “Quantum Boltzmann Equation”. When...

Timedependent NEGF
Open  Responses: 1
In the timedependent NEGF equation, given a sigma_in(t,t’) due to the dot, I am getting
an IV equation that is making it difficult for me to group terms. For instance, looking at...

Quantum dots
Open  Responses: 1
What I want to do is building an aluminum quantum dot coupled to
aluminum leads to observe Coulomb Blockade. To form the tunnel barriers
we oxidize the Al in a plasma without any detailed...

Highly Efficient Thermal Transport: The Application of Carbon Nanotube Array Interfaces
01 Feb 2007   Contributor(s):: Baratunde A. Cola
Carbon nanotubes (CNTs) have received much attention in recent years for their extraordinary properties that through careful engineering may be leverage for the development of numerous advantageous applications. However, to date, only few CNT based applications exist in the market place. So when...

McCoy Lecture: Nanodevices and Maxwell's Demon
04 Oct 2006   Contributor(s):: Supriyo Datta
This is a video taped live lecture covering roughly the same material as lecture 1 of "Concepts of Quantum Transport". Video only.

CQT Lecture 4: Coulomb blockade and Fock space
30 Nov 2006   Contributor(s):: Supriyo Datta
Objective: To illustrate the limitations of the model described in Lectures 2, 3 and introduce a completely different approach based on the concept of Fock space. I believe this will be a key concept in the next stage of development of transport physics.

CQT Lecture 3: Probabilities, Wavefunctions and Green Functions
30 Nov 2006   Contributor(s):: Supriyo Datta
Objective: To extend the simple model from Lecture 2 into the fullblown model combines the NEGF (NonEquilibrium Green Function) method with the Landauer approach.

CQT Lecture 2: Electrical Resistance  A Simple Model
30 Nov 2006   Contributor(s):: Supriyo Datta
