Excitonic Molecules
Part of the Lecture Notes in Physics book series (LNP, volume 57)


Based on new results of transmission and emission experiments on CdS single crystals in a very extended range of excitation intensities at 1.8 K, we discuss the annihilation and formation of excitonic mole cules in a model involving AΓ6-excitons and AΓ5-polaritons. It is shown that the presented results as well as those by Saito and Shionoya can be consistently explained in this model. A theoretical foundation of the model and a way to calculate emission and absorption spectra due to excitonic molecules are presented.
