In 1959, physicist Richard Feynman presented an
amazing talk entitled There's Plenty of Room at the Bottom, in which he proposed making very small circuits out of molecules. More than forty years later, people are starting to realize his vision. Thanks to Scanning Tunneling Microscope (STM) probes and "self-assembly" fabrication techniques, it is now possible to connect electrodes to a molecule and measure its conductance. In 2004, Mark Hersam et al. reported the first experimental measurement of a molecular resonant tunneling device on silicon. This new field of Molecular
Electronics may someday provide the means to miniaturize circuits beyond the limits of silicon, keeping Moore's Law in force for many years to come.

Molecular Transport Structures: Elastic Scattering, Vibronic Effects and Beyond
13 Feb 2006 | | Contributor(s):: Mark Ratner, Abraham Nitzan,
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...

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...
Field Regulation of Single Molecule Conductivity by a Charged Atom
29 Jul 2005 |
A new concept for a single molecule transistor is demonstrated. A single chargeable atom adjacent to a molecule shifts molecular energy levels into alignment with electrode levels, thereby gating current through the molecule. Seemingly paradoxically, the silicon substrate to which the molecule...
An Electrical Engineering Perspective on Molecular Electronics
26 Oct 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 that are less than 50 nm long, and billion transistor logic chips have arrived. Moore's Law continues, but the end of...
Simple Theory of the Ballistic MOSFET
11 Oct 2005 | | Contributor(s):: Mark Lundstrom
Silicon nanoelectronics has become silicon nanoelectronics, but we still analyze, design, and think about MOSFETs in more or less in the same way that we did 30 years ago. In this talk, I will describe a simple analysis of the ballistic MOSFET. No MOSFET is truly ballistic, but approaching this...
