• Band-structure-centric research unifies experimental band-edge measurements, effective masses, and transport parameters through pseudopotential form factors, linking GaAs/InAs family to broader semiconducting systems [1], [6], [11], [13], [12].

• Optical response studies center on exciton absorption, dielectric function, and index of refraction to deduce interband transitions and excitonic effects, spanning Si, Ge, GaAs, InAs, InSb, and related alloys [3], [7], [15], [9], [20].

• Defect and trap physics emerge as key drivers of recombination and annealing, with DLTS capturing trap spectra; recombination-enhanced defect reactions reveal defect dynamics under irradiation and recombination conditions [2], [10], [19].

• Carrier transport and diffusion length analyses reveal minority/majority carrier lifetimes and mass variations with temperature and doping, using LPE GaAs layers, diffusion measurements, and temperature-dependent mass data to inform mobility and device performance [5], [6], [12], [11].

• Surface/interface electronic properties highlight band bending, surface states absence/presence, and excitonic surface interactions in III–V and Si systems, linking photoemission behavior to surface adsorbates and oxide interfaces [8], [17].
