Band engineering in dilute nitride and bismide semiconductor lasers
Christopher A. Broderick, Muhammad Usman, Stephen J. Sweeney +1
Highly mismatched semiconductor alloys such as GaNAs and GaBiAs have several novel electronic properties, including a rapid reduction in energy gap with increasing x and also, for…

Theory of the electronic structure of dilute bismide and bismide-nitride alloys of GaAs: Tight-binding and k.p models
Muhammad Usman, Christopher A Broderick, Eoin P. O'Reilly
The addition of dilute concentrations of bismuth (Bi) into GaAs to form GaBiAs alloys results in a large reduction of the band gap energy Eg accompanied by a significant increase o…
