摘要:

对双量子阱中电子在隧道耦合态之间的共振跃迁引起的磁阻振荡进行了实验和理论研究。这些振荡随温度升高的抑制与费米分布的热加宽无关,反映了电子量子寿命的温度依赖性。振荡的周期和振幅的门控演示。

英文摘要:

We present experimental and theoretical studies of the magnetoresistance oscillations induced by resonance transitions of electrons between tunnel-coupled states in double quantum wells. The suppression of these oscillations with increasing temperature is irrelevant to the thermal broadening of the Fermi distribution and reflects the temperature dependence of the quantum lifetime of electrons. The gate control of the period and amplitude of the oscillations is demonstrated.
