中文摘要	the behavior of room temperature self-sustained current oscillations resulting from sequential resonance tunneling in a doped weakly-coupled gaas/alas superlattice (sl) is investigated under hydrostatic pressure. from atmosphere pressure to 6.5 kbar, oscillations exist in the whole plateau of the i-v curve and oscillating characteristics are affected by the pressure. when hydrostatic pressure is higher than 6.5 kbar, the current oscillations are completely suppressed although a current plateau still can be seen in the i-v curve. the plateau disappears when the pressure is close to 13.5 kbar. as the main effect of hydrostatic pressure is to lower the x point valley with respect to gamma point valley, the disappearance of oscillation and the plateau shrinkage before gamma - x resonance takes place are attributed to the increases of thermoionic emission and nonresonant tunneling components determined by the lowest gamma - x barrier height in gaas/alas sl structure.
