The utilization of functional organic materials holds great promise for applications in electronic devices. Semiconducting organic molecules are frequently used as channel material in field effect transistors, due to the ease by which they can be assembled ...
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 ...
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 ...
Polymer-protected sub-2-nm nanogaps that are fabricated via a novel electrical stressing approach exhibit substantial ionic-current reduction in near-physiological conditions. These devices enable direct DNA detection in aqueous solution by utilizing assem ...
A review. The unique structural, electronic, and mech. properties of single-walled carbon nanotubes (SWNTs) have opened the doors to developments that push the limits of science. These advancements not only further scientific discovery, but also result in ...
This review presents an overview of the recent progress made in the field of carbon nanotube (CNT)-based field-effect transistors (FETs). Starting from the simplest device architectures, various methods reported for fabricating CNT-FETs are presented. The ...
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 ...
Carbon nanotube field-effect transistors with Si(3)N(4) passivated source and drain contacts and exposed carbon nanotube channel show n-type characteristics in air. In contrast, by passivating only the source contact, a diode-like behavior with a maximum c ...
Surface science and molecular biology are often concerned with systems governed by fluid dynamics at the nanoscale, where different physical behaviour is expected. With advances in nanofabrication techniques, the study of fluid dynamics around a nano-objec ...
We report here on the interaction of the fluorescent dye rhodamine B (RB) with single-walled carbon nanotubes (SWCNTs). We observe that SWCNTs statically quench the fluorescence of RB by forming a stable ground state complex. Careful spectroscopic analysis ...
