Description

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.

  1. Nanotechnology: Silicon Technology, Bio-molecules and Quantum Computing

    13 May 2005 | | Contributor(s)::

    Nanotechnology: Silicon Technology, Bio-molecules and Quantum Computing

  2. 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 this...

  3. 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.

  4. 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...

  5. CMOS Nanotechnology

    07 Jul 2004 | | Contributor(s):: Mark Lundstrom

    In non-specialist language, this talk introduces CMOS technology used for modern electronics. Beginning with an explanation of "CMOS," the speaker relates basic system considerations of transistor design and identifies future challenges for CMOS electronics. Anyone with an elementary...
