Impact of disorder on the optoelectronic properties of GaN_yAs_{1-x-y}Bi_x alloys and heterostructures

We perform a systematic theoretical analysis of the nature and importance of alloy disorder effects on the electronic and optical properties of GaN_{y}As_{1-x-y}Bi_{x} alloys and quantum wells (QWs), using large-scale atomistic supercell electronic structure calculations based on the tight-binding method. Using ordered alloy supercell calculations we also derive and parametrise... Show more
