▲ First authors: Xu Shipu, Fu Huixia;

; Corresponding author: Peng Hailin Corresponding unit: Peking University Paper DOI: 10.1002/anie.5 This work applies the two-dimensional high mobility semiconductor Bi2O2Se crystal to the high selectivity and stability room temperature detection of trace oxygen in the sub ppm range. The mechanism of high-performance detection of trace oxygen by two-dimensional Bi2O2Se was elucidated using scanning tunneling microscopy (STM), in-situ X-ray photoelectron spectroscopy (in-situ XPS), and Hall device characterization, combined with first principles calculations. Research has found that when the surface of two-dimensional Bi2O2Se is exposed to oxygen, a high specific surface area amorphous Se reconstructed atomic layer is formed, which can effectively adsorb oxygen. The mobility and Fermi level of the two-dimensional Bi2O2Se semiconductor are effectively modulated to change its conductivity; In addition, the two-dimensional oxygen flow measurement|water flow meter

Bi2O2Se array oxygen sensor has enhanced signal-to-noise ratio and can detect oxygen concentrations below 0.25 ppm. A. The current development trend of trace oxygen sensing is that it has a wide range of applications in various fields such as biological detection, energy, chemical engineering, and intelligent manufacturing. Commercial electrochemical oxygen sensors utilize the concentration electromotive force generated by oxygen on both sides of the diaphragm material to output signals, but their configuration is cumbersome and difficult to miniaturize. In comparison, the core structure of a resistive oxygen sensor is a two terminal resistor composed of sensing materials, which greatly simplifies the structure and is very conducive to integrated applications. Two dimensional materials can further enhance the performance of resistive oxygen sensors due to their large specific surface area and high mobility. Currently, there are literature reports that two-dimensional MoS2 has good oxygen sensing ability, which can detect oxygen with a concentration of about 10%. However, the detection of trace oxygen (ppm level) remains a major challenge, mainly due to the limited number of active sites on the surface of materials such as MoS2, which results in insufficient adsorption capacity for trace oxygen. To fundamentally solve this problem, it is necessary to design and prepare two-dimensional material based oxygen sensors with abundant active sites based on the atomic and band structure of the material itself. B. Introduction of High Mobility Two Dimensional Semiconductor Material - Bi2O2Se In 2017, Peng Hailins research group at Peking University reported for the first time a two-dimensional Bi2O2Se crystal with high mobility.
