| 英文摘要 | Room-temperature microwave (mw) oscillations are observed in gaas/alas (10 nm/2 nm) doped weakly coupled superlattices (sls) in the first plateau of the i-v curve. oscillations induced by sequential resonant tunneling are detected in a temperature range from 15 to 300 k by applying dc bias on the si, diodes. the temperature dependence of current at small fixed bias voltage is also measured. through analysis, it is found that the dominant transport mechanisms are sequential resonant tunneling and phonon-assisted tunneling when the temperature is below 300 k. the low bias voltage at which oscillations are realized is helpful to restrain thermionic emission through the x valley of alas barriers in the room-temperature transport.
