We report a technique which allows self-assembly of conducting nanoparticles into long continuous chains. Transport properties of such chains have been studied at low temperatures. At low bias voltages, the charges are pinned and the chain resistance is exponentially high. Above a certain threshold VT, the system enters a conducting state. The threshold voltage is much bigger than the Coulomb gap voltage for a single particle and decreases linearly with increasing temperature. A sharp threshold…

Electronic transport in conducting polymer nanowire array devices

It is shown that charging of the conducting regions leads to Coulomb blockade effects that can account for this behaviour, and temperature dependent conductivity and current-voltage properties of novel polyaniline nanowire array devices are reported on.

Charge Transport in Chain of Nanoparticles

We have bridged a pair of gold electrodes through chains and arrays of gold nanoparticles, coated with citrate molecules. We performed a systematic and comparative analysis of current-voltage

Quasi-one-dimensional transport in conducting polymer nanowires

Recent advances in the synthesis of nanowires based on conducting conjugated polymers are described. The results of recent experimental studies of the electrical properties of polymer nanowires are



Electrostatic trapping of single conducting nanoparticles between nanoelectrodes

For molecular electronics, one needs the ability to electrically address a single conducting molecule. We report on the fabrication of stable Pt electrodes with a spacing down to 4 nm and demonstrate

Collective transport in arrays of small metallic dots.

For short-ranged interactions, one of the correlation length exponents near threshold is found from a novel argument based on interface growth, and the dynamical exponent for the current above threshold is predicted analytically.
