Mӧssbauer Studies of the Local Surrounding of Atoms in Amorphous and Crystalline Ge2Sb2Te5 Films

A. V. Marchenko, Yu. A. Petrushin, P. P. Seregin

The local environment of atoms in crystalline and amorphous films Ge₂Sb₂Te₅ was determined by method of M�?§ssbauer spectroscopy with the ¹¹⁹Sn, ¹²¹Sb and ¹²⁵Te isotopes. The current stage of phase memory (FP) research based on chalcogenide semiconductors is associated with the use of incongruently melting compounds in the Ge-Sb-Te system lying on the GeTe-Sb₂Te₃ quasi-binary section line, and the composition of Ge₂Sb₂Te₅ is of the greatest interest.
