摘要

这项研究提出了一种气体传感器系统，以硒化二维（2D）薄膜为主要传感材料，并与金属栅极耦合浮动栅极器件集成，以实现自校准。二维气体传感材料在不同器件上的电阻水平固有的差异一直是一个重大挑战，导致传感电路内的输出信号出现重大偏差。为解决这一问题，我们引入了一种新型自收敛操作技术，它能有效减轻电阻变化的影响，从而提高气体传感结果的精度和可靠性。即使器件与器件之间存在电阻变化，拟议的气体传感器系统也能提供一致而准确的结果，这使其成为气体传感技术的一项重要贡献。这项工作对于需要高精度气体检测和定量的各种应用具有巨大潜力。

Advanced self-convergent calibration for selenized two-dimensional film gas sensors

This research presents a gas sensor system featuring a selenized two-dimensional (2D) film as its primary sensing material, integrated with metal-gate-coupled floating gate devices to enable self-convergent calibration. The inherent variability in resistance levels of 2D gas-sensing materials across different devices has been a significant challenge, resulting in substantial deviations of the output signal within the sensing circuit. To address this issue, we introduce a novel self-convergent operational technique, which effectively mitigates the impact of resistance variations thereby enhancing the precision and reliability of gas-sensing outcomes. The proposed gas sensor system promises to deliver consistent and accurate results, even with device-to-device resistance variations, making it a valuable contribution to gas-sensing technology. This work holds substantial potential for various applications requiring highly precise gas detection and quantification.
