英文摘要Crystallization behaviors and configurations of germanium-tellurides (GexTe100-x) at a wide compositional range (12.5 <= x <= 85) have been investigated. It is found GexTe100-x film exhibits one- or two-step crystallization behavior with a complicated competition between GeTe and Te (or Ge) phases. The composition dependences of crystallization temperature and activation energy have been revealed. They exhibit four singularities at x = 20.4 (GeTe4), x = 33 (GeTe2), x = 49 (GeTe), and x = 22 (Ge22Te78). Based on the method of X-ray photoelectron spectroscopy, the structural sketches for the Ge(x)Te(100-x )glasses that is helpful to understand the evolution of crystallization behavior are built up. It is evident that, the presence of homopolar Te-Te and heteropolar Ge-Te bonds is the main reason for the structural and thermal stability of Ge-deficient films, and Ge-Ge bond in GeGe4 tetrahedron appears when x > 50 and effectively enhances the stability of Ge-rich films.
