  4. Carrier Transport at the Nanoscale

    27 Nov 2007 | | Contributor(s):: Mark Lundstrom

    Fall 2007Note: A more current teaching of this course with online lectures is available as ECE 656: Electronic Transport in Semiconductors (Fall 2011).This is a course about how charge flows in semiconductors with an emphasis on transport at the nanoscale. After a brief review basic concepts, the...

  5. Engineering at the nanometer scale: Is it a new material or a new device?

    06 Nov 2007 | | Contributor(s):: Gerhard Klimeck

    This seminar will overview NEMO 3D simulation capabilities and its deployment on the nanoHUB as well as an overview of the nanoHUB impact on the community.

  6. MCW07 Modeling Molecule-Assisted Transport in Nanotransistors

    06 Nov 2007 | | Contributor(s):: Kamil Walczak

    Molecular electronics faces many problems in practical device implementation, due to difficulties with fabrication and gate-ability. In these devices, molecules act as the main conducting channel. One could imagine alternate device structures where molecules act as quantum dots rather than...

  7. MCW07 Simple Models for Molecular Transport Junctions

    13 Sep 2007 | | Contributor(s):: Misha Galperin, Abraham Nitzan, Mark Ratner

    We review our recent research on role of interactions in molecular transport junctions. We consider simple models within nonequilibrium Green function approach (NEGF) in steady-state regime.

  9. MCW07 Electronic Level Alignment at Metal-Molecule Contacts with a GW Approach

    05 Sep 2007 | | Contributor(s):: Jeffrey B. Neaton

    Most recent theoretical studies of electron transport in single-molecule junctions rely on a Landauer approach, simplified to treat electron-electron interactions at a mean-field level within density functional theory (DFT). While this framework has proven relatively accurate for certain systems,...

  10. MCW07 Modeling Charging-based Switching in Molecular Transport Junctions

    23 Aug 2007 | | Contributor(s):: Sina Yeganeh, Misha Galperin, Mark Ratner

    We will discuss several proposed explanations for the switching and negative differential resistance behavior seen in some molecular junctions. It is shown that a proposed polaron model is successful in predicting both hysteresis and NDR behavior, and the model is elaborated with image charge...

  11. Quantum Ballistic Transport in Semiconductor Heterostructures

    27 Aug 2007 | | Contributor(s):: Michael McLennan

    The development of epitaxial growth techniques has sparked a growing interest in an entirely quantum mechanical description of carrier transport. Fabrication methods, such as molecular beam epitaxy (MBE), allow for growth of ultra-thin layers of differing material compositions. Structures can be...

  12. Electronics From the Bottom Up: a view of conductance

    17 Aug 2007 | | Contributor(s):: Supriyo Datta

    Resistance is one of the first concepts an electrical engineer learns, but things get interesting at the nanoscale. Experimentalists have found that no matter how short the resistor is, its resistance cannot drop below a fundamental lower limit. They also found that resistance increases in...

  17. Orbital Mediated Tunneling in a New Unimolecular Rectifier

    25 May 2007 | | Contributor(s):: Robert Metzger, NCN at Northwestern University

    In 1997 we showed that hexadecylquinolinium tricyanoquinodimethanide is a unimolecular rectifier, by scanning tunneling microscopy and also as a Langmuir-Blodgett (LB) monolayer, sandwiched between Al electrodes. We have now seen rectification in a new molecule: this rectification can be followed...
