Abstract: The surface topology of epitaxial films of lead tin telluride solid solution (including with In additive, Pb$_{1-x}$Sn$_{x}$Te:In) has been examined using atomic force microscopy. The films have been grown on BaF$_2$(111) single-crystal substrates and on a CaF$_2$/BaF$_2$ buffer layer covering a Si(111) wafer. It has been shown that the relief statistical parameters depend on film growth conditions and the incorporation mechanism of indium, an excess amount of which has been detected on the surface by ex situ XPS.
Keywords: Topological insulator, surfacem solid solution, A$^{\mathrm{IV}}$B$^{\mathrm{VI}}$, lead tin telluride.
