Optical Spectra and Band Structure of AgxGaxGe1–xSe2 (x = 0.333, 0.250, 0.200, 0.167) Single Crystals: Experiment and Theory

“…Calculation at the baseline led to satisfactory results, as indicated by the values of the factors of reliability and difference diffraction profiles. The obtained values of the unit cell parameters of phase Ag x Ga x Ge 1– x Se 2 interatomic distances Kat–An are shown in Table , and agree well with the previous data. ,,, As the table shows, the crystallographic positions of the atoms in the structure are filled chalcogen four compositions are always fully considered, and differ in the position of the fill factor of the metal component and the ratio of p-atoms in position 16 b element i 8 a . Somewhat higher values of thermal parameters of silver atoms were observed in all four related structures.…”

“…The detailed structure of the crystal-chemical analysis was not carried out by the authors. In the Olekseyuk et al work, some attention is paid to the mechanism of formation of solid solutions, although complete data of crystal research, in particular the atomic coordinates, are not given. The titled crystals were synthesized by a method described in ref .…”
