Atomistic tight-binding study of electronic structure and interband optical transitions in GaBi $_{x}$ As $_{1 - x}$ /GaAs quantum wells

Muhammad Usman, Eoin P. O'Reilly

Large-supercell tight-binding calculations are presented for GaBi $_{x}$ As $_{1 - x}$ /GaAs single quantum wells (QWs) with Bi fractions $x$ of 3.125% and 12.5%. Our results highlight s…
