Abstrakt: A time-resolved photoluminescence study of strained and unstrained InGaAsP/InP double heterostructures has been performed at low photogenerated carrier densities (i.e. ≤1016cm−3) using a novel high-efficiency germanium photon-counting detector. The photoluminescenee decay times are observed to decrease with increasing strain. Samples grown on substrates with lattice orientation (3 1 1)B are shown to have shorter excess carrier lifetimes than those grown on lattices orientated (0 0 1) or (3 1 1)A.
