AI中文摘要：
基于MoS₂等层状过渡金属二硫化物（TMDCs）的气体传感器近来备受关注，被视为传统金属氧化物基气体传感器件的有前景替代品。近期关于TMDC气体传感器的研究主要集中于吸附机制的理论描述，或测试器件的制备及其气体传感性能的研究。然而，目前仍缺乏合适的方法来建模TMDC器件的气体传感行为，以及在理论结果与器件暴露于气体时的实验响应之间建立可靠联系。为填补这一空白，本研究开发了一种新的基于朗缪尔的吸附模型，该模型可同时计算传感器的灵敏度和选择性，并将其应用于MoS₂基气体传感器。结果表明，利用已发表的吸附能和电荷转移等合适数据作为输入，该模型可很好地复现已报道的MoS₂气体传感器的实验灵敏度。
英文摘要：
Gas sensors based on layered TMDCs (transition-metal dichalcogenides) such as MoS2 have attracted considerable attention recently and are considered as a promising alternative to the conventional metal-oxide-based gas sensing devices. Recent studies on TMDC gas sensors have mainly addressed either the theoretical description of adsorption mechanisms or the fabrication of test devices and the investigation of their gas sensing performance. However, a suitable approach for modeling the gas sensing behavior of TMDC devices and for establishing a reliable connection between theoretical results and the response of experimental devices when exposed to gases remains absent. To bridge this gap, in the present work a new Langmuir-based adsorption model, capable of calculating both the sensor sensitivity and selectivity, is developed and applied to MoS2-based gas sensors. It is shown that by using appropriate published data for the adsorption energy and the charge transfer as input data, the reported experimental sensitivities of MoS2 gas sensors can be well reproduced by the model.
