Molecular Electronics Pathway for Molecular Memory Devices
Online Presentations | 06 Feb 2004 | Contributor(s):: Ranganathan Shashidhar
We have been developing a scale molecular electronic device using a 30 nm sized plant virus particle as the scaffold. This talk describes the bioengineering aspects of how the virus particle is converted to a molecular electronic circuit and its electrical characterization. The talk describes...

Electronic Transport Through Self-Assembled Monolayers
Online Presentations | 25 Feb 2004 | Contributor(s):: Takhee Lee
Characterization of charge transport in molecular scale electronic devices has to date shown exquisite sensitivity to specifics of device fabrication and preparation. Thus, intrinsic molecular band structure has been problematic to extract from published results. Here we demonstrate...

Contacting Molecules - Chemistry in Molecular Electronics
Online Presentations | 12 Apr 2004 | Contributor(s):: Ilona Kretzschmar
The study of the basic electron transport mechanism through molecular systems has been made accessible by fabrication techniques that create metallic contacts to a small number of organic molecules. In my talk, I will discuss some of the groundbreaking discoveries such as the measurement of the...

Inelastic Effects in Molecular Conduction
Online Presentations | 12 Apr 2004 | Contributor(s):: Abraham Nitzan
Molecular electron transfer, as treated by the Marcus theory, strongly depends on nuclear motion as a way to achieve critical configurations in which charge rearrangement is possible. The electron tunneling process itself is assumed to occur in a static nuclear environment. In the application of...

Electrical Conduction through Molecules
Papers | 08 Jul 2003 | Contributor(s):: Ferdows Zahid, Magnus Paulsson, Supriyo Datta
In recent years, several experimental groups have reported measurements of the current-voltage (I-V) characteristics of individual or small numbers of molecules. Even three-terminal measurements showing evidence of transistor action has been reported using carbon nanotubes as well as...

Mini-Workshop on Carbon-Nanotube FETs
Workshops | 13 May 2003
This informal one-day workshop was intended to discuss theory, modeling, and simulation for CNT-electronics, specifically FETs. The objective was to kick off an NSF-funded project on the modeling and simulatin of CNT-electronics. A small group of experimentalists, theorists, and computational...

Resistance of a Molecule
Papers | 29 Apr 2003 | Contributor(s):: Magnus Paulsson, Ferdows Zahid, Supriyo Datta
In recent years, several experimental groups have reported measurements of the current-voltage (I-V) characteristics of individual or small numbers of molecules. Even three-terminal measurements showing evidence of transistor action has been reported using carbon nanotubes [1, 2] as well as...

Theory of Ballistic Nanotransistors
Papers | 27 Nov 2002 | Contributor(s):: Anisur Rahman, Jing Guo, Supriyo Datta, Mark Lundstrom
Numerical simulations are used to guide the development of a simple analytical theory for ballistic field-effect transistors. When two-dimensional electrostatic effects are small, (and when the insulator capacitance is much less than the semiconductor (quantum) capacitance), the model reduces to...
