Effect of the surface and size of specimens on polariton kinetics and polariton trapping
Travnikov V. V., Krivolapchuk B. B.
The effect of the finite dimensions of specimens on polariton kinetics and polariton trapping is investigated experimentally for the first time. It is found that the lifetime of the polaritons decreases in thin specimens. An experimental estimate of the diffusion length of polaritons (Z,~5-7 μπι) is obtained for high-quality CdS specimens.
