In this paper, the phonon, dynamic and thermal properties of indium nitride in two phases are investigated. The calculations are performed using the pseudopotantial method in the framework of density functional theory and by using the quantum-espresso Package. In the calculations, the exchange-correlation terms of LDA, GGA and PBE0 approximation are used. Investigation of phononic  properties s...

In this study, supply electrical, heating and cooling loads in the building by a separate production system and a cogeneration system, particle swarm optimization algorithm in five different scenarios were studied and analyzed (For example, Data and Information a high-rise building base 72, in the city of Kerman is used). The results show that, cold and heat power system of micro gas turbine wi...

In this paper, according to the  density functional theory and semiharmonic approximation and solving kohen's equations using plane wave, band structure, phonon scattering; Dielectric tensor, Bourne effective charge, Raman cross-section; We calculated the infrared and specific heat capacity of indium phosphide in two-phase structures on zincblend (ZB) and salt rock (Rs). The results show that t...
