摘要: The band structure of dilute-As GaNAs alloy with the As composition range from 0% to 12.5% is studied by using First-Principle density-functional calculation. Our analysis shows that exhibits direct gap properties. a 3.645 eV down 2.232 content varying 12.5%, which covers blue and green spectral regime. This finding indicates as potential candidate for photonic devices applications. bowing parameter 14.5 ±0.5 also obtained line fitting experimental data. effective masses electrons holes in alloy, well split-off energy parameters, were presented. Minimal interband Auger recombination suggested attributing off-resonance condition this process.
