摘要:

在量子霍尔机制下研究了具有大纵横比的反量子点小阵列中的Aharonov-Bohm(AB)效应。在磁场与栅电压(B-Vg)平面中的AB振荡随温度的演化揭示了屏蔽的温度依赖性。自洽屏蔽潜力的可压缩带周围的antidot观察到获得逐渐陡峭的斜率随着温度的升高。

英文摘要:

The Aharonov-Bohm (AB) effect in a small array of antidots with large aspect ratio is investigated in the quantum Hall regime. The evolution with temperature of the AB oscillations in the magnetic field vs gate voltage (B-Vg) plane reveals the temperature dependence of the screening. The self-consistently screened potential of the compressible band surrounding an antidot is observed to gain progressively steeper slope with increasing temperature.
