Auger recombination in quantum well gallium antimonide

The temperature dependence of Auger recombination in quantum well GaSb is investigated. The result is a similar behaviour to that in bulk GaSb, increasing at low temperatures and decreasing at high temperatures with a maximum in between. This temperature dependence suggests a minimum in the temperature dependence of the gain whereas experiment gives a monotonic decrease. This discrepancy is resolved, showing that the gain measurements correspond to the increasing branch of the Auger curve.
