In this study, a model of a Schottky-barrier carbon nanotube fieldeffect transistor (CNT-FET), with ferromagnetic contacts, has been developed. The emphasis is put on analysis of current-voltage characteristics as well as shot (and thermal) noise. The method is based on the tight-binding model and the nonequilibrium Green’s function technique. The calculations show that, at room temperature, th...
In this article, a new structure is presented for MOS (Metal Oxide Semiconductor)-like junctionless carbon nanotube field effect transistor (MOS-like J-CNTFET), in which dual material gate with different work-functions are used. In the aforementioned structure, the size of the gates near the source and the drain are 14 and 6 nm, respectively, and the work-functions are equal and 0.5 eV less tha...
In the past decade, semiconducting carbon nanotube thin films have been recognized as contending materials for wide-ranging applications in electronics, energy, and sensing. In particular, improvements in large-area flexible electronics have been achieved through independent advances in postgrowth processing to resolve metallic versus semiconducting carbon nanotube heterogeneity, in improved ga...
The performance of a semiconducting carbon nanotube (CNT) is assessed and tabulated for parameters against those of a metal-oxide-semiconductor field-effect transistor (MOSFET). Both CNT and MOSFET models considered agree well with the trends in the available experimental data. The results obtained show that nanotubes can significantly reduce the drain-induced barrier lowering effect and subthr...
CARBON NANOTUBE THIN FILM TRANSISTORS FOR BIOMEDICAL APPLICATIONS Vanessa Velasco August 5, 2010 The application of carbon nanotubes (CNTs) has captivated the curiosity of today's experts due to the escalating potential in the field of electronic detection of biomolecules. Their extreme environmental sensitivity and small size make them ideal candidates for future biosensing technologies. Recen...
We have successfully aligned single-walled carbon nanotubes (SWNTs) in patterns with nanoscale width, micron-scale length and controllable pitch on SiO2/Si substrates using a poly(dimethysiloxane) (PDMS) microchannel mold. The microchanneled mold was patterned with a funnel-shaped channel to minimize nanotube jamming during capillary-driven inflow. Two (i.e. preand post-capillary) gas blows wer...
Polarized infrared optical emission was observed from a carbon nanotube ambipolar field-effect transistor (FET). An effective forward-biased p-n junction, without chemical dopants, was created in the nanotube by appropriately biasing the nanotube device. Electrical measurements show that the observed optical emission originates from radiative recombination of electrons and holes that are simult...
