Description

Nano Electro-Mechanical Systems (NEMS) are tiny machines built at the nanometer scale. Current NEMS applications are simple machines, such as the tiny cantilever shown at the right. An electrical circuit measures the deflection of the lever. A larger version of this device, with dimensions at the micrometer or millimeter scale, is commonly used as an airbag sensor in automobiles. A sudden stop causes a strong deflection of the lever, which signals that the airbags should be deployed. At the nano scale, such a lever is sensitive enough to measure the weight of individual atoms or molecules resting upon it.

  1. Introduction to Carbon Nanotube Electronics

    12 Oct 2005 | | Contributor(s):: Susan Sinnott

    Carbon nanotubes (CNT) have interesting, structure-dependent electronic properties. In particular, CNTs can be a metallic or semiconducting depending on the way in which the carbon atoms are arranged in the CNT walls. The purpose of this learning module is to familiarize students with the basic...

  2. Introduction to Molecular Conduction

    21 Jul 2005 | | Contributor(s):: Ferdows Zahid, Magnus Paulsson, Avik Ghosh, Supriyo Datta

    A scanning probe microscope brushes the tips of molecules rising up from a gold substrate. After making contact, the probe measures a very strange current-voltage relationship--linear portions separated by flat spots or sharp increases. Definitely not Ohm's law. Is the experiment correct?...

  3. Introduction to the CENEMS Simulation Tool (Learning Module)

    15 Apr 2006 | | Contributor(s):: , Narayan Aluru

    This learning module is an introduction to the CENEMS simulation tool. Nanoelectromechanical systems (NEMS) often contains multiple nanoscale conductors. CENEMS is a user-friendly 2-D classical electrostatic analysis tool that computes the charge density distribution on the surface of the...
