Tunable SO2-sensing performance of arsenene induced by Stone-Wales defects and external electric field

Reported here is a first-principle study of the adsorption of four SF6 decomposition products on pristine arsenene and arsenene with Stone-Wales defects (SW). The results revealed that pristine arsenene exhibited high sensitivity and selectivity to SO2, and Stone-Wales defects enhanced the SO2-sensing performance. The presence of ambient O2, H2O, and SF6 only slightly affected the adsorption on both pristine and SW arsenene. We also investigated...
