“…to Wannier-Mott excitons, which are the only form of a photon excitation in semiconductor QDs. Following [12], we assume that these excitons will be localized, and the experimentally observed response [1][2][3] is the IEE at local excitons.In Russia, the IPE technique was implemented by Yu.G. Vainer [4], who rightly asserted that the temporal resolution of the photon echo method is determined in the general case not by the duration of the exciting pulses Δt, but by the radiation coherence time τc, i.e.…”
