摘要: The relation between different types of band-to-band Auger processes in InGaAsP is studied. According to a nonparabolic band model that makes use \vec{k} \cdot \vec{p} perturbation theory, the effect involving excited split-off (CHSH process) dominant. light hole (CHLH far less than CHSH process or conduction (CHCC process). A simple parabolic overestimates CHCC by about one order magnitude, and CHLH more ten orders magnitude.
