First-principles calculations of structural and electronics properties of YInN alloy

We study the structural and electronic properties of YxIn1-xN in the concentrations x = 0, ¼, ½, ¾, and 1 in the B1, B2, B3 and B4 structures using density functional theory (DFT). The calculations show that for Y0.75In0.25N, the B1 structure is the most favorable energetically. It was determined t...

Description
Summary:We study the structural and electronic properties of YxIn1-xN in the concentrations x = 0, ¼, ½, ¾, and 1 in the B1, B2, B3 and B4 structures using density functional theory (DFT). The calculations show that for Y0.75In0.25N, the B1 structure is the most favorable energetically. It was determined that between  in the  supercell, the most energetically stable structure is the B3 phase. Additionally, between  concentrations x of Yttrium, the compound is most energetically favorable in the B4 phase. Technical data that are in agreement were recently reported by other authors. Finally, between 0.12 , the most stable phase is B1. Additionally, there is no phase transition between the four structures considered. The DOS and band structure show that Y0.75In0.25N in the B1 and B3 phases exhibits semiconductor behavior, with a direct gap of ~0.6 eV and ~0.7 eV, respectively while Y0.75In0.25N in the B4 phase has an indirect one of ~0.8 eV.
