Molecular Electronics Pathway for Molecular Memory Devices
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...

Molecular Transport Structures: Elastic Scattering, Vibronic Effects and Beyond
13 Feb 2006 | | Contributor(s):: Mark Ratner, Abraham Nitzan, Misha Galperin
Current experimental efforts are clarifying quite beautifully the nature of charge transport in so-called molecular junctions, in which a single molecule provides the channel for current flow between two electrodes. The theoretical modeling of such structures is challenging, because of the...

Moore's Law Forever?
13 Jul 2005 | | Contributor(s):: Mark Lundstrom
This talk covers the big technological changes in the 20th and 21st century that were correctly predicted by Gordon Moore in 1965. Moore's Law states that the number of transistors on a silicon chip doubles every technology generation. In 1960s terms that meant every 12 months and currently...

Nano-Scale Device Simulations Using PROPHET
20 Jan 2006 | | Contributor(s):: Yang Liu, Robert Dutton
These two lectures are aimed to give a practical guide to the use of a general device simulator (PROPHET) available on nanoHUB. PROPHET is a partial differential equation (PDE) solver that offers users the flexibility of integrating new models and equations for their nano-device simulations. The...

Nanodevices: A Bottom-up View
13 Jun 2005 | | Contributor(s):: Supriyo Datta
It is common to differentiate between two ways of building a nanodevice: a top-down approach where we start from something big and chisel out what we want and a bottom-up approach where we start from something small like atoms or molecules and assemble what we want.

Nanoelectronics: The New Frontier?
18 Apr 2005 | | Contributor(s):: Mark Lundstrom
After forty years of advances in integrated circuit technology, microelectronics is undergoing a transformation to nanoelectronics. Modern day MOSFETs now have channel lengths of only 50 nm, and billion transistor logic chips have arrived. Moore’s Law continues, but the end of MOSFET scaling is...

Nanoscale Thermodynamics
13 Dec 2006 | | Contributor(s):: John Enriquez
This is the fifth contribution from the students in the University of Texas at El Paso Molecular Electronics course given in the fall of 2006. This introduces nanothermodynamics, the study of small system equilibrium. Nanothermodynamics was established in the early 60’s, but has recently...

Notes on the Ballistic MOSFET
08 Oct 2005 | | Contributor(s):: Mark Lundstrom
When analyzing semiconductor devices, the traditional approach is to assume that carriers scatter frequently from ionized impurities, phonons, surface roughness, etc. so that the average distance between scattering events (the so-called mean-free-path, λ) is much shorter than the device. When...

Orbital Mediated Tunneling in a New Unimolecular Rectifier
25 May 2007 | | Contributor(s):: Robert Metzger, NCN at Northwestern University
In 1997 we showed that hexadecylquinolinium tricyanoquinodimethanide is a unimolecular rectifier, by scanning tunneling microscopy and also as a Langmuir-Blodgett (LB) monolayer, sandwiched between Al electrodes. We have now seen rectification in a new molecule: this rectification can be followed...
