摘要

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 the effect of biaxial strain and an external electric field on the SO₂ detection of SW arsenene. The SO₂ adsorption strength on SW arsenene was drastically enhanced or weakened, depending on the direction of the electric field, which is desirable for realizing the ultra-sensitive adsorption and desorption of SO₂.
