New phenomena in CDW systems at small scales

TL;DR

This paper reviews how the electrical properties of quasi-one-dimensional charge-density wave conductors change qualitatively when their transverse sizes are reduced, highlighting finite-size effects and their origins.

Contribution

It provides a concise review of finite-size effects in CDW systems at small scales and discusses their underlying physical mechanisms.

Findings

Finite-size effects significantly alter CDW properties.

Size reduction leads to qualitative changes in electrophysical behavior.

Current understanding of the origin of these effects is summarized.

Abstract

The electrophysical properties of quasi-one-dimensional conductors with a charge-density wave change qualitatively upon a decrease in their transverse sizes. A brief review of various finite-size effects and the present-day knowledge of their origin is presented.
