摘要：

The homogeneous linewidth Γh of the lowest exciton state in CdTe/(Cd,Zn)Te single quantum wells (QW's) has been analyzed as a function of QW thickness, temperature, and exciton density. The zero-temperature and density limit of Γh suggests the presence of an ordering mechanism that decreases the effective interface roughness for the narrower QW's in the CdTe/(Cd,Zn)Te system. The exciton-acoustic-phonon and the exciton-exciton scattering are of comparable strength as in GaAs QW's, indicating the absence of strong localization effects, present in other II-VI QW systems. © 1995 The American Physical Society.
