The thickness of the films synthesized is ~100 nm, the size of coherent scattering regions is ~70 nm, and the value of microstrains is ~0.20%. It is established, for the first time, that the assynthesized PbS films and the same films annealed in the temperature range 293–423 K have a cubic crystal structure (space group Fm3m) different from the B1 type structure. In the crystal lattice of the structure revealed, sulfur atoms are located not only in the 4(b) positions but also in the 8(c) positions. The occupancies of the 4(b) and 8(c) positions by the S atoms are ~0.84 and 0.08, respectively Доп.точки доступа: Rempel, A. A.; Ремпель Андрей Андреевич
