A real spatial oscillations of the excited wave packet identified quantum beats of the Wannier-Stark states as Bloch oscillations. Using a new technique for measurement of the spatial dynamics of Bloch wave packets in semiconductor superlattices we investigate the features of spatial-temporal dynamics on the initial experimental conditions and the composition of the wave packet.enIII-V semiconductorIII-V Halbleiterquantum wellsQuantenfilmoptical measurementoptische Messung621667conference paper
