Slow propagation of photon-like polaritons generated by exciton-exciton scattering in ZnO thin films
We report on the first observation of the thickness-dependent photoluminescence-decay time of exciton-exciton scattering in ZnO thin films, which indicates the slower propagation of photon-like polaritons compared to that in bulk by two orders magnitude.
