摘要:

我们在高达30 T的高垂直磁场中操作单电子的按需源,对应于低于1/3的填充因子。该设备提取和发射单电荷在一个可调的能量和二维电子气,进入定义良好的整数和分数量子霍尔(QH)状态。因此,它可以用于敏感的电输运研究,例如在QH边缘状态的激发和弛豫过程。

英文摘要:

We operate an on-demand source of single electrons in high perpendicular magnetic fields up to 30T, corresponding to a filling factor below 1/3. The device extracts and emits single charges at a tunable energy from and to a two-dimensional electron gas, brought into well defined integer and fractional quantum Hall (QH) states. It can therefore be used for sensitive electrical transport studies, e.g. of excitations and relaxation processes in QH edge states.
