Electronic and valleytronic properties of crystalline boron-arsenide tuned by strain and disorder

Autor: Craco, L., Carara, S. S., Barboza, E. da Silva, Pereira, T. A. S., Milosevic, M. V.

Ab initio density functional theory (DFT) and DFT plus coherent potential approximation (DFT+CPA) are employed to reveal, respectively, the effect of in-plane strain and site-diagonal disorder on the electronic structure of cubic boron arsenide (BAs)
