FIG. 1.

(Color online) (a) Photoluminescence spectrum of the GaAs multi-QW sample measured at and . Four peaks corresponding to the four quantum wells are clearly seen. (b) Variation of the peak emission energy with the QW thickness. The solid line corresponds to a curve with . (c) Linewidth as a function of well width. The solid line corresponds to a curve . One would naively expect an dependence (broken line) since the PL energy has dependence.

(Color online) Change in the linewidth, , as a function of magnetic field for quantum wells of different thicknesses. Qualitative trends depend on the well width.

Image of FIG. 3.
FIG. 3.

(Color online) A schematic of the probable physical situation. The figure depicts quantum well interface fluctuations on two length scales, . The other interface is drawn flat for simplicity.
