Title of Document: DEVELOPMENT OF CARBON NANOTUBE FIELD-EFFECT TRANSISTOR ARRAYS FOR DETECTION OF HER2 OVEREXPRESSION IN BREAST CANCER Konrad Hsu Aschenbach, Ph.D., 2011 Directed By: Professor Romel D. Gomez, Department of Electrical and Computer Engineering We developed a carbon nanotube biosensor platform that was deployed at the National Cancer Institute and successfully detected the HER2 on...

Carbon nanotube field-effect transistor (CNTFET) refers to a field-effect transistor that utilizes a single carbon nanotube or an array of carbon nanotubes as the channel material instead of bulk silicon in the traditional MOSFET structure. Since it was first demonstrated in 1998, there have been tremendous developments in CNTFETs, which promise for an alternative material to replace silicon in...

The AC performance capabilities of Schottky-barrier carbon nanotube field-effect transistors are examined via simulations using a self-consistent Schrödinger-Poisson solver. It is shown that good high-frequency performance demands use of a small-bandgap nanotube, whereas good digitalswitching performance can be achieved with larger-bandgap tubes. For typical transistor geometries it is shown th...

A novel and robust scheme for radix-4 Booth scheme implemented in Carbon Nanotube Field-Effect Transistor (CNTFET) technology has been presented in this paper. The main advantage of the proposed scheme is its improved speed performance compared with previous designs. With the help of modifications applied to the encoder section using Pass Transistor Logic (PTL), the corresponding capacitances o...
