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.

Moore's Law Forever?
5.0 out of 5 stars
10 Aug 2005 | Online Presentations | 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...
Nanodevices: A Bottom-up View
20 Jun 2005 | Online Presentations | 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...
