Abstract

Using Messbauer spectroscopy on ¹¹⁹Sn impurity atoms, it was demonstrated that in amorphous (GeTe)_x(Sb₂Te₃) films (where x = 0.5, 1, 2, 3) tin atoms replace atoms of tetravalent germanium, which forms a tetrahedral system of chemical bonds with atoms in its local environment. In crystalline films, tin replaces divalent six-coordinated germanium in positions 4b of the NaCl-type crystal lattice.

非晶薄膜 (GeTe)x(Sb2Te3) 中德国原子局部环境的性质

摘要通过对 119Sn 杂质原子进行梅斯鲍尔光谱分析，证明在非晶态 (GeTe)x(Sb2Te3) 薄膜（x = 0.5、1、2、3）中，锡原子取代了四价锗原子，而四价锗原子与其局部环境中的原子形成了化学键四面体体系。在晶体薄膜中，锡取代了二价六配位锗，位于 NaCl 型晶格的 4b 位。

期刊介绍： Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
