The author provides an opinion on direct experimental evidence available to support the “ionosorption theory” often employed to interpret “electrophysical” measurements made during a gas sensing experiment. This article then aims to provide an alternative framework of a “surface conductivity” model based on recent advances in theoretical and experimental investigations in solid state physics, and to use this framework as a guide toward design rules for future improvement of gas sensor performance.

我们需要“离子吸附”氧种类吗?(或者,“基于可变表面氧空位浓度的金属氧化物中气体敏感性的表面电导率模型”)

作者提供了关于可用于支持“离子吸附理论”的直接实验证据的意见,该理论通常用于解释在气体传感实验期间进行的“电物理”测量。然后,本文旨在基于固态物理学理论和实验研究的最新进展提供“表面电导率”模型的替代框架,并使用该框架作为设计规则的指南,以提高气体传感器的性能。
