Περίληψη:
We have developed a quantum-mechanical theory for the interaction of
light and electron-hole excitations in semiconductor quantum dots. Our
theoretical analysis results in an expression for the photoluminescence
intensity in the non-linear regime. The validity of the theoretical
results is tested analyzing experimental data reported for the
temperature dependence of the emission spectra of an individual
lens-shaped In0.4Ga0.6As self-assembled quantum dot in a wide
temperature range up to 300 K. Our theoretical predictions for the
redshift of the emission peak with increasing temperature, in the range
2-300 K, agree with the experiment.
