标题： Chaos in resonant-tunneling superlattices

摘要： 空间时间混沌被预测会出现在具有连续共振隧穿为主要电荷输运机制的n掺杂半导体超晶格中。 在直流电压偏置下，由于电场畴壁的运动和循环，电流的振荡（未阻尼的时间相关振荡）已在最近的实验中被观察到。 混沌是通过适当的外部微波信号强迫这种自然振荡的结果。 显示英文摘要

摘要： Spatio-temporal chaos is predicted to occur in n-doped semiconductor superlattices with sequential resonant tunneling as their main charge transport mechanism. Under dc voltage bias, undamped time-dependent oscillations of the current (due to the motion and recycling of electric field domain walls) have been observed in recent experiments. Chaos is the result of forcing this natural oscillation by means of an appropriate external microwave signal.
