A scientific article entitled “Synthesis and characterization of new indium gallium selenides of the InSe-GaSe system” by Imamaddin Amiraslanov and Zakir Jahangirli, leading researchers of the Nano-Research Center of Baku State University was published by Journal of Solid State Chemistry (İF: 3.498) (v. 304, 2021).

The new solid solution phases crystallized in the hexagonal and tetragonal system were revealed in the GaSe-InSe system, and a new orthorhombic phase with a new type of structural blocks has been proposed. The structural features of the In_1-xGa_xSe solid solutions (where 0 ​≤ ​x ​≤ ​1) were studied using X-Ray Diffraction (XRD), Differential Thermal Analysis (DTA), and Raman spectroscopy. The chemical interaction between Ga and In atoms in the hexagonal In_1-xGa_xSe phases was identified. The reversible phase transition from hexagonal to the tetragonal structure was found to occur in the In_0.7Ga_0.3Te phase. Using the Density Functional Theory (DFT) method, the electronic, optical, and vibrational properties for the Pnnm orthorhombic InGaSe₂ phase were studied.
