“…This suggests that the formation of pyramids is associated with the well-known fact of micromasking in the places where dislocations emerge on the surface [8]. The shape of the triangular pyramids in this case is explained by the (111) orientation of lead telluride films, while the (100) orientation is characterized by the appearance of tetrahedral pyramids [9]. The pyramids in this experiment are truncated due to partial sputtering of the vertices and at the same time formation of the nanorelief.…”

The paper discusses the physical aspects of surface modification of Pb1-xSnxTe (x = 0.00-0.80) epitaxial films during ion-plasma treatment in argon plasma. Lead–tin telluride films 1−2 μm thick were grown on (111) BaF2 substrates by molecular beam epitaxy. The ion-plasma treatment of the samples was carried out in a high-density low-pressure radio frequency (RF) inductively coupled plasma at an ion energy of 75 eV. The duration of the process is 240 s. The evolution of the surface morphology of the films and the formation of micro- and nanostructures at different ratios of lead and tin are studied.
