Macromolecular Simulation: A Computational Perspective
Online Presentations | 16 Feb 2004 | Contributor(s):: Robert D. Skeel
The study of cold atomic gases is exploding, driven largely by the rapid experimental developments. This field has become highly interdisciplinary, connecting a great variety of interesting problems: weakly and strongly correlated quantum condensed matters, nuclear matters, and physics of low...

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...

Nanoelectronic Scaling Tradeoffs: What does Physics Have to Say?
Presentation Materials | 23 Sep 2003 | Contributor(s):: Victor Zhirnov
Beyond CMOS, several completely new approaches to information-processing and data-storage technologies and architectures are emerging to address the timeframe beyond the current SIA International Technology Roadmap for Semiconductors (ITRS). A wide range of new ideas have been proposed for...

Nanoelectronics and the Future of Microelectronics
Online Presentations | 22 Aug 2002 | Contributor(s):: Mark Lundstrom
Progress in silicon technology continues to outpace the historic pace of Moore's Law, but the end of device scaling now seems to be only 10-15 years away. As a result, there is intense interest in new, molecular-scale devices that might complement a basic silicon platform by providing it...

Quantum Electromechanical Systems: Are we there yet?
Online Presentations | 05 Feb 2004 | Contributor(s):: Andrew Cleland
Electrons moving in a conductor can transfer momentum to the lattice via collisions with impurities and boundaries, giving rise to a fluctuating mechanical stress tensor. Driving electrons out of equilibrium by applying the voltage across the conductor, one may control this electromechanical noise.

Quantum-dot Cellular Automata
Online Presentations | 24 Nov 2003 | Contributor(s):: Craig S. Lent
The multiple challenges presented by the problem of scaling transistor sizes are all related to the fact that transistors encode binary information by the state of a current switch. What is required is a new paradigm, still capable of providing general purpose digital computation, but which can...

Structure and Ion Permeation of the Gramicidin Channel using Molecular Dynamics
Online Presentations | 12 Apr 2004 | Contributor(s):: Toby Allen
Molecular dynamics (MD) has become an essential tool for obtaining microscopic insight into biological function. The gramicidin channel as an excellent benchmark system for this purpose. Using extensive MD simulations with explicit solvent and membrane, we determine the backbone structure and...

Towards a Terahertz Solid State Bloch Oscillator
Online Presentations | 29 Jan 2004 | Contributor(s):: S. James Allen
The concepts of Bloch oscillation and Zener breakdown are fundamental to electron motion in periodic potentials and were described in the earliest theoretical developments of electron transport in solids. But only in the past 10 years have experiments clearly demonstrated various aspects of Bloch...

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...
