Phase equilibria in the quasi-ternary system Ag2Se-Ga2Se3-In2Se3 and physical properties of (Ga0.6In0.4)2Se3, (Ga0.594In0.396Er0.01)2Se3 single crystals

The quasi-ternary system Ag2Se-Ga2Se3-In2Se3 was investigated by differential thermal, X-ray phase, X-ray structure, microstructure analysis and microhardness measurements. Five quasi-binary phase diagrams, six polythermal sections, isothermal section at 820 K and the liquidus surface projection were constructed. The character and temperature of the invariant processes were determined. The specific resistance of the single crystals (Ga0.6In0.4)2Se3, (Ga0.594In0.396Er0.01)2Se3 was measured, 7.5 × 105 and 3.15 × 105 Ω m, respectively, optical absorption spectra in the 600-1050 nm range were recorded at room temperature, and the band gap energy was estimated which is 1.95 ± 0. 01 eV for both samples.
