FIG. 1.

Normalized PL decay kinetics for AlGaN MQW structures with different well widths: (1) 5, (2) 4.1, and (3) . Measurements were performed under excitation energy density of .

FIG. 2.

Normalized PL decay kinetics for AlGaN MQW structure with well width of at different excitation energy densities (indicated). Inset shows the excitation energy density dependence of the PL intensity at time zero for the same AlGaN MQW structure.

FIG. 3.

Decay of induced transient grating efficiency for AlGaN MQW structures with different well widths (indicated). The curves were shifted along vertical axis for clarity. Solid lines show the best fit using a single exponential function.
