Comment on "Contribution of drifting carriers to the Casimir-Lifshitz and Casimir-Polder interactions with semiconductor materials"

TL;DR

This paper critiques a recent proposal to modify Lifshitz theory for semiconductor interactions, demonstrating that the suggested changes are inconsistent with thermodynamics and experimental data.

Contribution

The paper provides a critical analysis showing that the proposed modification to Lifshitz theory is incompatible with thermodynamic principles and experimental observations.

Findings

The proposed modification is thermodynamically inconsistent.

The modification does not align with experimental results.

The critique clarifies the correct approach to semiconductor interactions in Lifshitz theory.

Abstract

Recently D. A. R. Dalvit and S. K. Lamoreaux arXiv:0805.1676 [Phys. Rev. Lett. v.101, 163203 (2008)] suggested the modification of the reflection coefficients in the Lifshitz theory taking into account the screening effects and diffusion currents. We demonstrate that the suggested modification is thermodynamically and experimentally inconsistent.
