| 中文摘要 | a novel ac driving configuration is proposed for biased semiconductor superlattices, in which the thz driving is provided by an intense bichromatic cw laser in the visible light range. the frequency difference between two components of the laser is resonant with the bloch oscillation. thus, multi-photon processes mediated by the conduction (valence) band states lead to dynamical delocalization and localization of the valence (conduction) electrons, and to the formation and collapse of quasi-minibands. thus, driven bloch oscillators are predicted to generate persistent thz emission and harmonics of the dipole field, which are tolerant of the exciton and the relaxation effects. |
