In this thesis, models are presented for the design and analysis of carbon nanotube field-effect transistors (CNFETs). Such transistors are being seriously considered for applications in the emerging field of nanotechnology. Because of the small size of these devices, and the nearone-dimensional nature of charge transport within them, CNFET modeling demands a rigorous quantum-mechanical basis. ...

Carbon nanotube field effect transistors (CNFETs) are being extensively studied as possible successors to Silicon MOSFETs. Implementable CNTFET circuits have operational characteristics to approach the advantage of using MVL in voltage mode. In this paper we used CNTFETs to implement the improved Gödel basic operators. This paper presents arithmetic operations, implication and multiplication in...

to investigate the interaction and adsorption of drug and carbon nanotube on human serum albumin, three anti-cancer drugs ([pd(phen)(r-gly)]no3, r = methyl, propyl and amyl) with different hydrophobic tails and anticancer activities were selected. these drugs have better anti-tumor activity and less side effects than that known cis-platinum drug. human serum albumin is also important for drug d...

A 20 × 20 pixel pressure sensor array based on a printed active-matrix single-wall carbon-nanotube thin-film transistor backplane is presented. Using a gravure printing process that is compatible with fully printed large-area roll-to-roll processing, a 97% device yield is obtained on the 400-transistor backplane. As a proof of concept, pressure sensors are integrated to map the applied tactile ...

Direct formation of iron phosphate nanoparticles on solid substrates with a narrow size distribution (average diameter = 2.2 nm) has been achieved by a simple spontaneous reaction of ferric chloride and phosphoric acid on hydroxyl-terminated SiO2/Si substrates. Single-walled carbon nanotubes (SWNTs) are grown in high yield from the synthesized iron phosphate nanoparticles by thermal chemical va...

Carbon nanotubes have potential in the development of high-speed and power-efficient logic applications. However, for such technologies to be viable, a high density of semiconducting nanotubes must be placed at precise locations on a substrate. Here, we show that ion-exchange chemistry can be used to fabricate arrays of individually positioned carbon nanotubes with a density as high as 1 × 10(9...

The recent developments of Carbon NanoTube Field Effect Transistor (CNTFET) technology indicate the perspective of the Nanoelectromechanical systems (NEMS). Carbon nanotubes (CNT) are ideal candidates for NEMS due to their chemical and physical structures, low masses and exceptional stiffness. Study of NEMS devices in the light of quantum mechanics requires understanding the interplay between t...

This paper presents a review on our recent work on carbon nanotube field effect transistors, including the development of ohmic contacts, high-κ gate dielectric integration, chemical functionalization for conformal dielectric deposition and pushing the performance limit of nanotube FETs by channel length scaling. Due to the importance of high current operations of electronic devices, we also re...

This study demonstrates the rapid and label-free detection of Interleukin-6 (IL-6) using carbon nanotube micro-arrays with aptamer as the molecular recognition element. Single wall carbon nanotubes micro-arrays biosensors were manufactured using photo-lithography, metal deposition, and etching techniques. Nanotube biosensors were functionalized with 1-Pyrenebutanoic Acid Succinimidyl Ester (PAS...
