Self-heating of dense exciton Gas in CdTe single crystals

Heating of the dense exciton gas is observed in highly photoexcited CdTe single crystals radiating mainly due to the exciton‐exciton collisions at the lattice temperature T = 77 K. The effective exciton temperature turned out to be an increasing function of the excitation density while the heating i...

Zusammenfassung:	Heating of the dense exciton gas is observed in highly photoexcited CdTe single crystals radiating mainly due to the exciton‐exciton collisions at the lattice temperature T = 77 K. The effective exciton temperature turned out to be an increasing function of the excitation density while the heating is independent of the exciting quantum energy. A model of exciton selfheating due to the binding and radiative recombination processes under strong interparticle interaction is proposed for the explanation of the experimental data.
