摘要：
By the method of M & ouml;ssbauer spectroscopy on the isotope Sn-119, it was shown that tetravalent germanium atoms in amorphous films (GeTe)(x)(Sb2Te3) (where x = 0.5, 1, 2, 3) form a tetrahedral system of chemical bonds, and in their local environment there are mainly tellurium atoms. In crystalline films (GeTe)(x)(Sb2Te3) is divalent hexoordinated germanium at positions 4 b of the NaCl type crystal lattice. By the method of M & ouml;ssbauer spectroscopy on Sb-121 and Te-125 atoms, it was shown that the amorphization of (GeTe)(x)(Sb2Te3) films does not change the local environment of antimony and tellurium atoms.
