Carbon nanotubes (CNT) have been investigated extensively in the recent years for application in nano-electromechanical systems (NEMS). CNTs have extraordinary electrical and mechanical properties. They are stiff, with low density, high electrical conducti ...
We report a novel resist-assisted dielectrophoresis method for single-walled carbon nanotube (SWCNT) assembly. It provides nanoscale control of the location, density, orientation and shape of individual SWCNTs. Sub-50 nm accuracy and a yield higher than 85 ...
Technology scaling improves the energy, performance, and area of the digital circuits. With further scaling into sub-45nm regime, we are moving toward very low supply (VDD) and threshold voltages (VT), smaller VDD/VT ratio, high leakage current, and large ...
Silicon technology has advanced at exponential rates both in performances and productivity through the past four decades. However the limit of CMOS technology seems to be closer and closer and in the future we might see an increasing number of hybrid appro ...
There has been an argument on carbon nanotube (CNT) based gas detectors with a field-effect transistor (FET) geometry: do the response signals result from charge transfer between adsorbed gas molecules and the CNT channel and/or from the gas species induce ...
The prospect of realizing nanoscale transistors using individual semiconducting carbon nanotubes offers enormous potential, both as an alternative to silicon technology beyond conventional scaling limits and as a way to implement high-speed devices and cir ...
A self-limiting dielectrophoresis technique, aimed at deterministically assembling individual or bundles of single-walled carbon nanotubes (SWCNTs) and multiwalled carbon nanotubes (MWCNTs), is experimentally investigated. A limiting resistor is used to co ...
We present a gate-dependent Raman spectroscopy and electric transport measurements of an individually connected multiwall carbon nanotube in the field-effect transistor configuration at room temperature. We discuss the origin of the four distinct sharp mod ...
Bio-detection specially dedicated to distributed diagnostics is emerging as a quite important application for Nanobioelectronics. Bio-detection is required to be highly sensitive in order to succeed in sensing small amount of bio-markers in patient’s blood ...

In this review, the suitability of the major types of carbon nanostructures as conducting channels of field-effect transistors (FETs) is compared on the basis of the dimensionality and size of their pi-conjugated system. For each of these materials, recent ...
