One-dimensional conduction in Charge-Density Wave nanowires

TL;DR

This paper investigates how the electrical conduction in charge-density wave nanowires composed of multiple one-dimensional metallic chains varies with the number of chains, revealing power-law behavior indicative of one-dimensional physics.

Contribution

It provides a systematic analysis of transport in coupled one-dimensional chains, highlighting the transition in behavior as the number of chains increases.

Findings

Transport exhibits power-law dependence on temperature and voltage for fewer than 2000 chains.

The behavior confirms one-dimensional conduction characteristics in the studied nanowires.

Transport properties change with the number of chains, indicating dimensional crossover.

Abstract

We report a systematic study of the transport properties of coupled one-dimensional metallic chains as a function of the number of parallel chains. When the number of parallel chains is less than 2000, the transport properties show power-law behavior on temperature and voltage, characteristic for one-dimensional systems.
