Effect of photoexcitation intensity on exciton kinetics
Travnikov V. V., Krivolapchuk V. V.
For the first time, it has been found that the intensity of the exciting light affects the kinetics of the relaxation to the steady-state energy distributions of the excitons in the exciton band. The lifetime of the free excitons is shown to increase with increasing excitation intensity. The changes in the lifetime are estimated.
