Fig. 6. (a)–(c) Top (upper panel) and side views (lower panel) of the magnetization charge density difference plots for NO, NO2 and O2 adsorbed on pristine arsenene, and (d) for O2 adsorbed at Pt-doped arsenene, in which blue and red regions correspond to up and down magnetization, respectively. The magnetization charge density isosurface value is 0.001e Å−3.
