Figure 1
Temperature dependence of X-ray powder diffraction profiles for sputtered Ag3.4In3.7Sb76.4Te16.5 amorphous film in the heating process. The amorphous halo patterns are observed at low temperatures from 295 to 416 K. However, at around 416 K the Bragg peaks of the A7-type structure appear in the halo pattern. As the temperature is raised further, the A7-type single phase separates into two phases, AgInTe2 and an Sb–Te binary compound, at around 545 K. At 2θ angles lower than 5°, Bragg peaks were hardly observed at any measurement temperatures.
