We investigate the family of semiconductors consisting of GaAs, GaSb, InAs and InSb, considering their electronic band structure and deformation potentials subject to various strains based on hybrid density functional theory. Guided by these first-principles results, we develop strain-compliant local pseudopotentials for use in the empirical pseudopotential method (EPM). We demonstrate that the newly proposed empirical pseudopotentials perform well close to band edges and under anisotropic crystal deformations. Using the EPM, we explore the heavy hole-light hole mixing characteristics under different stress directions, which may be useful in manipulating their transport properties and optical selection rules. The very low 5 Ry cutoff targeted in the generated pseudopotentials paves the way for large-scale EPM-based electronic structure computations involving these lattice mismatched constituents.EnglishDeformation potentialDensity functional theoryElectronic band structureEmpirical pseudopotential methodHybrid functionalsStrain in semiconductorsAnisotropyBand structureCrystal symmetryDeformationElectronic structureGallium alloysGallium arsenideIndium antimonidesOptical propertiesSemiconducting galliumStrainTime varying systemsDeformation potentialElectronic band structureEmpirical pseudopotential methodHybrid density functional theoryHybrid functionalsLocal pseudopotentialsMixing characteristicsOptical selection rulesDensity functional theoryArticle10.1088/0022-3727/49/8/085104
