Biosensing applications of Plasmon Resonance in gold nanoparticles
out of 5 stars
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...
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...
Pulsed Laser Deposition of Thin Films
02 Aug 2007 | | Contributor(s):: Josh Kaufman
Thin metal films have many applications from optical limiters to nanocircuits. Methods for fabricating these films differ in theory and complexity. Pulsed Laser Deposition (PLD) is a popular method for fabricating thin films. A number of thin films were fabricated using PLD. Silver films of...

The NASA Institute for Nanoelectronics and Computing and NSF Network for Computating Nanotechnology offers qualifying students the opportunity to become Summer Undergraduate Research Interns (SURIs). SURIs join an ongoing cross-disciplinary research project team comprised of faculty and graduate...
Characterization of Colloids Using the BET method and X-ray Scattering
03 Aug 2006 | | Contributor(s):: Oluwaseyi Ogebule
Colloids are promising materials for a wide range of applications such as selective separations, catalytic processing, and enhanced chemical activity. However, these applications are limited without proper knowledge of colloidal bulk properties. Therefore, the characterization of colloids is...
Three-Dimensional Simulations of Field Effect Sensors for DNA Detection
03 Aug 2006 | | Contributor(s):: Eddie Howell, Gerhard Klimeck
Here, the development of a DNA field-effect transistor (DNAFET) simulator is described. In DNAFETs the gate structure of a silicon on insulator (SOI) field-effect transistor is replaced by a layer of immobilized single-stranded DNA molecules which act as surface probe molecules. When...
Investigation of the Electrical Characteristics of Triple-Gate FinFETs and Silicon-Nanowire FETs
08 Aug 2006 | | Contributor(s):: Monica Taba, Gerhard Klimeck
Electrical characteristics of various Fin field-effect transistors (FinFETs) and silicon-nanowires were analyzed and compared using a modified three-dimensional self-consistent quantum-mechanical simulator in order to investigate device performance. FinFETs have been proposed to fulfill the...
Chemical Modification of GaAs with TAT Peptide and Alkylthiol Self-Assembled Monolayers
03 Aug 2006 | | Contributor(s):: Hamsa Jaganathan
The use of self-assembled monolayers (SAM) on semiconductors creates a basis for the design and creation of bioelectronics, such as biosensors. The interface between the surface and an organic monolayer can change significant electrical and physiochemical properties of a biological device....
Technique for High Spatial Resolution, Focused Electrical Stimulation for Electrically Excitable Tissue
08 Aug 2006 | | Contributor(s):: Matteo Mannino
Cochlear implant devices have made use of electrode pulses as a method of nerve fiber stimulation since their early conception. Electrode stimulation is limiting in both quality and consistency, and a new method is required if significant improvements to implant devices are to be made. By using a...
