  1. Active Photonic Nanomaterials: From Random to Periodic Structures

    06 Feb 2006 | | Contributor(s):: Hui Cao

    Active photonic nanomaterials, which have high gain or large nonlinearity, are essential to the development of nanophotonic devices and circuits. In this talk, I will provide a review of our recent research activities related to the fabrication of active photonic nanomaterials and the development...

  2. Optimization of Transistor Design for Carbon Nanotubes

    20 Jan 2006 | | Contributor(s):: Jing Guo

    We have developed a self-consistent atomistic simulator for CNTFETs.Using the simulator, we show that a recently reported high-performanceCNTFET delivers a near ballistic on-current. The off-state, however, issignificantly degraded because the CNTFET operates like anon-conventional Schottky...

  3. A 3D Quantum Simulation of Silicon Nanowire Field-Effect Transistors

    17 Jan 2006 | | Contributor(s):: Mincheol Shin

    As the device size of the conventional planar metal oxide semiconductor field effect transistor(MOSFET) shrinks into the deep sub micron regime, the device performance significantly degradesmainly due to the short-channel effect. The silicon nanowire field-effect transistor (SNWFET) isconsidered...

  4. How Can Your Educational Modules Contain Interactive Online Simulation?

    28 Feb 2005 | | Contributor(s):: Gerhard Klimeck

    The Network for Computational Nanotechnology (NCN) is a multi-university, NSF-funded initiative with a mission to lead in research, education, and outreach to students and professionals, while at the same time deploying a unique web-based cyber-infrastructure to serve the nation''s National...

  14. Field Regulation of Single Molecule Conductivity by a Charged Atom

    29 Jul 2005 |

    A new concept for a single molecule transistor is demonstrated. A single chargeable atom adjacent to a molecule shifts molecular energy levels into alignment with electrode levels, thereby gating current through the molecule. Seemingly paradoxically, the silicon substrate to which the molecule is...
