Abstract
The derivative -dN(t)/dlgt of photo-induced excess electrons N(t) in G aAb-Al-0.3 Ga-0.7 As and In0.15Ga0.85As-Al0.2Ga0.8As heterostructures with respect to lgt shows a spectrum with pronounced peak-structure. T he apparent capture energies, the lifetime prefactors, the apparent li fetime distribution, and the derivative decay quantities of individual lifetimes were analyzed to distinguish capture mechanisms.
