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.

Nanoelectronics: The New Frontier?
out of 5 stars
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...
2005 Molecular Conduction and Sensors Workshop
27 Jul 2005 |
This is the 3rd in a series of annual workshops on Molecular Conduction. The prior workshops have been at Purdue University, W. Lafayette, IN (2003) and Nothwestern University, Evanston, IL (2004). The workshop has been an informal and open venue for discussing new results, key challenges, and...
