  1. Biosensing applications of Plasmon Resonance in gold nanoparticles

    02 Aug 2007 | | Contributor(s):: Karina Moore

    Light can be used to excite plasmon resonance in gold nanoparticles. Plasmon resonance occurs on the nanoscale as the particles become excited and plasmon oscillations arise in each particle of a pair of metal nanoparticles. There is plasmon coupling between the neighboring particles as the...

  2. The Effect of Physical Geometry on the Frequency Response of Carbon Nanotube Field-Effect Transistors

    03 Aug 2007 | | Contributor(s):: Dave Lyzenga

    In order for carbon nanotube (CNT) electrical devices to be fabricated, it is necessary to obtain modifiable operation characteristics. Developing parametric equations to achieve this controllability in the vertical field-effect transistor (FET) design is an important first step toward...

  3. Pulsed Laser Deposition of Thin Films

    02 Aug 2007 | | Contributor(s):: Josh Kaufman
