Derivation of 12- and 14-band Hamiltonians for dilute bismide and bismide-nitride semiconductors
Christopher A. Broderick, Muhammad Usman, Eoin P. O'Reilly
Using an tight-binding model we demonstrate how the observed strong bowing of the band gap and spin-orbit-splitting with increasing Bi composition in the dilute bismi…
12-band model for dilute bismide alloys of (In)GaAs derived from supercell calculations
Christopher A. Broderick, Muhammad Usman, Eoin P. O'Reilly
Incorporation of bismuth (Bi) in dilute quantities in (In)GaAs has been shown to lead to unique electronic properties that can in principle be exploited for the design of high effi…
Impact of alloy disorder on the band structure of compressively strained GaBiAs
Muhammad Usman, Christopher A. Broderick, Zahida Batool +4
The incorporation of bismuth (Bi) in GaAs results in a large reduction of the band gap energy (E) accompanied with a large increase in the spin-orbit splitting energy ($\bigtri…
