Sj. Fancey et al., TIME-RESOLVED PHOTOLUMINESCENCE STUDY OF STRAINED-LAYER INGAASP INP HETEROSTRUCTURES/, Journal of crystal growth, 183(1-2), 1998, pp. 269-273
A time-resolved photoluminescence study of strained and unstrained InG
aAsP/InP double heterostructures has been performed at low photogenera
ted carrier densities (i.e. less than or equal to 10(16) cm(-3)) using
a novel high-efficiency germanium photon-counting detector. The photo
luminescence decay times are observed to decrease with increasing stra
in. Samples grown on substrates with lattice orientation (311)B are sh
own to have shorter excess carrier lifetimes than those grown on latti
ces orientated (001) or (311)A.
