Comment on: "Current-voltage characteristics and zero-resistance state in 2DEG"
M.V.Cheremisin
TL;DR
This paper critiques a proposed N-shape current-voltage model for explaining zero-resistance states in 2DEG, showing it cannot account for key features observed in radiation-induced magnetoresistance oscillations experiments.
Contribution
It provides a critical analysis demonstrating that the existing N-shape I-V model is insufficient to explain experimental observations in 2DEG systems.
Findings
The N-shape I-V model fails to reproduce key experimental features.
Radiation-induced magnetoresistance oscillations are not explained by the proposed model.
The critique suggests the need for alternative explanations or models.
Abstract
We demonstrate that N(S)-shape current-voltage characteristics proposed to explain zero-resistance state in Corbino(Hall bar) geometry 2DEG (cond-mat/0302063, cond-mat/0303530) cannot account essential features of radiation-induced magnetoresistance oscillations experiments.
