摘要: We report on the electronic structure and optical properties of conducting ternary transition metal nitrides consisting metals different groups periodic table elements. For study bonding, structure, TixTa1−xN film growth, spectroscopy ab initio calculations were used. Despite valence electron configuration constituent elements, Ta(d3s2) Ti(d2s2), we show that TiN TaN are completely soluble due to hybridization d sp electrons N, respectively, stabilizes systems rocksalt structure. The have been studied using spectroscopic methods detailed calculations, revealing plasma energy fully dense is varying between 7.8 9.45 eV. Additional absorption bands manifested N p→Ti/Ta d interband t2g→eg ...
