In this paper, the scattering process of Ne+ and Ar+ ions bombarding the surface of black phosphorene at grazing (small) angles is computer-simulated using the binary collision approximation method. The characteristic trajectories and energy spectra of the Ne+ and Ar+ ions scattered from this surface are calculated. The trajectories of the scattered ions revealed the presence of an armchair-like semichannel on the black phosphorene surface. Two intense peaks were initially observed in the obtained energy spectra; they were found to correspond to the ions scattered from the surface atomic layer and the bottom of the semichannel. An increase in the angle of incidence led to ion scattering from neighboring semichannels, and peaks with low intensity corresponding to them were observed. The obtained results allow for the characterization of the surface layer and its structure.
