Abstract

- We have performed a joint theoretical and experimental study to investigate the terahertz radiation from Bloch oscillations in a GaAs/Al0.3Ga0.7As superlattice under the condition that there is no Zener tunneling. The total radiation intensity has been calculated with a semiclassical approach in the low field regime where the Wannier-Stark ladder (WSL) cannot be resolved, and with an exact numerical solution in the high field regime where the WSL is well formed. With an adjustment of the intensity units, without fitting material parameters, the calculated results agree almost perfectly with the measured data given in arbitrary units. Consequently, our work gives convincing evidence that the measured THz radiation is due to the Bloch oscillations.
