Abstract
The photoluminescence linewidth in CdTe-based piezoelectric quantum wells increases with the quantum-well width: this demonstrates the contribution of fluctuations of the built-in field, which appear strongly correlated with the width of the x-ray-diffraction rocking curve. A more complete analysis of the Bragg peak in the reciprocal space allows us to propose a quantitative model.Keywords
