Diffusivity, mobility and time-of-flight measurements: scientific fictions and 1/f-noise realization

TL;DR

This paper investigates how equilibrium thermal 1/f-type mobility fluctuations affect time-of-flight measurements, providing an explanation for observed experimental transient photocurrent behaviors.

Contribution

It demonstrates that thermal 1/f-noise fluctuations can account for specific time dependencies in photocurrent measurements, offering a new perspective on interpreting experimental data.

Findings

Thermal 1/f-noise influences transient photocurrent behavior.

Fluctuations can explain experimental time dependencies.

Provides a theoretical framework for observed phenomena.

Abstract

Influence of equilibrium thermal 1/f-type mobility fluctuations on time-of-flight measurements is considered. We show that it can explain experimental time dependencies of transient photocurrents.
