A band-to-band Coulomb interaction model for refractive indices of Al{sub}xGa{sub}(1-x)As and InGaAs ternary materials at photon energies near and above the band-gap

摘要

Refractive indices of ternary materials at photon energies somewhat above the bandgap have been modeled from Kramers-Kronig transform through an absorption model with Coulomb interaction and a double-Lorentzian broadening in employing Vegard's law.
