Electron Transport in One-Dimensional Disordered Lattice

TL;DR

This paper investigates how correlations in a 1D disordered lattice can lead to delocalization of electron states, enabling electron transport in systems typically characterized by localization.

Contribution

It demonstrates that specific parameter combinations in correlated disordered 1D systems can eliminate localization, allowing electron transport to occur.

Findings

Localization can be suppressed in correlated disordered 1D systems.

Electron transport parameters are identified for certain conditions.

Disorder sources include defects, impurities, and electron-phonon interactions.

Abstract

We have studied the peculiarities of electron transport in one-dimensional (1D) disordered chain at the presence of correlations between on-site interaction and tunneling integrals. In the considered models the disorder in host-lattice sites positions is caused by presence of defects, impurities, existence of electron-phonon interaction, e.t.c. It is shown, that for certain combination of parameters the localization of electron state, inherited by a various of 1D disordered systems, disappear and electron transport becomes possible. The parameters of this transport are established.
