TL;DR: In this article, a thermodynamic assessment of the binary In-Se system was performed based on the evaluation of literature, and a set of thermodynamic parameters were obtained, and the calculated phase diagram was presented.
Abstract: Available experimental thermodynamic and phase diagram data were critically reviewed. A thermodynamic assessment of the binary In-Se system was performed based on the evaluation of literature. The intermediate compounds taken into account are In4Se3, InSe, In6Se7, In9Se11, In5Se7, and polymorphic In2Se3 (α, β, γ and δ). All these compounds were treated as stoichiometric phases. The liquid phase was described using the association model with the associate species of ‘In2Se3’. A set of thermodynamic parameters was obtained, and the calculated phase diagram is presented.

TL;DR: In this article, the formation energies of charged component compounds were defined as functions of the Fermi-level based on the results of the ab initio calculations and adjusted to fit experimental data.
Abstract: The thermodynamic modeling of GaN was refined to describe the semiconducting properties of GaN semiconductors with the use of CEF (Compound Energy Formalism). Oxygen doped GaN was taken as an example. The formation energies of charged component compounds were defined as functions of the Fermi-level based on the results of the ab initio calculations and adjusted to fit experimental data. The yellow luminescence (YL) effect in unintentionally doped GaN was described.

Abstract: A thermodynamic assessment of the binary Ga–Ti system was performed based on the evaluation of the literature and our experimental results. Diffusion couple and alloy samples with appropriate compositions were prepared and analyzed by electron probe microanalysis and X-ray diffraction to determine the stability of intermetallic compounds. The Ga-rich part of phase diagram was checked by differential thermal analyses. The subreguler solution model was used to describe the solution phases liquid (L), b.c.c. (β), h.c.p. (α 1 ) and f.c.c. (γ 1 ). The compound energy model was employed to describe compounds with homogeneity ranges of Ti 3 Ga (α 2 ), Ti 5 Ga 4 (ρ) and TiGa(γ 2 ). The compounds Ti 2 Ga, Ti 5 Ga 3 , Ti 2 Ga 3 , TiGa 2 and TiGa 3 were treated as stoichiometric phases. A set of thermodynamic parameters was obtained and the calculated phase diagram was presented.
