| 英文摘要 | We have investigated the influence of transverse magnetic field b up to 14 t at 1.6 k on the tunneling processes of electric field domains in doped weakly coupled gaas/alas superlattices. three regimes, i.e, stable field domains, current self-sustained oscillations and averaged field distribution are successively observed with increasing b. the mechanisms of switching-over among these regimes are due to b-induced modification of the dependence of the effective electron drift velocity on electric field. the simulated calculation gives a good agreement with the observed experimental results.
