  • High sensitivity gas sensor to detect SF6 decomposition

    Oct 01, 2020In addition, we predict that SbP is suitable for SO 2 sensing to detect SF 6 decompositions by comparing adsorption energy and charge transfer of different substrates. Therefore, monolayer SbP can be a promising candidate for high sensitivity SO 2 sensor to detect SF 6 decompositions.Author: Haojie Guo, Kai Zheng, Heping Cui, Fusheng Zhang, Jiabing Yu, Lu-Qi Tao, Xiandong Li, Xianping Chen
