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 ...
In this thesis, the electronic structures of low-dimensional carbon allotropes have been studied. In particular, the spatially-resolved photocurrent responses of devices comprising carbon nanostructures were investigated through scanning photocurrent micro ...
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 ...
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 ...

We have fabricated a type of unique single-walled carbon nanotube field-effect transistor, in which the channel length is only 90 nm and aluminum and gold are used as its drain and source electrodes, respectively. The channel conductance oscillations cause ...
The dispersion of highly hydrophobic carbon materials such as carbon nanotubes in biological media is a challenging issue. Indeed, the nonspecific adsorption of proteins occurs readily when the nanotubes are introduced in biological media; therefore, a met ...
An improved method for self-assembly fabrication of single-walled carbon nanotube (SWCNT) field effect transistors (FETs) is presented, combining the unique design of biased/floating potential electrode geometry and the technique of aligning CNTs by pre-de ...
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 ...
A class of peptides from the bombolitin family, not previously identified for nitroaromatic recognition, allows near-infrared fluorescent single-walled carbon nanotubes to transduce specific changes in their conformation. In response to the binding of spec ...
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 ...
