Abstract
A. systematic Study of a set of GaAs/AlGaAs quantum well infrared phot odetectors with various shapes of the first barrier (which acts as the device emitter or collector barrier depending on the applied bias pol arity) is reported on. Three types of barriers are investigated: a tri angular, a thick, and a high barrier. It is found that the effect of t he detailed emitter or collector barrier shapes on the detector perfor mance is negligible.
