量子霍尔Aharonov-Bohm干涉仪边缘态输运性质的理论推导

E. Cicek, A. Siddiki

摘要:

在这里,我们报告我们的结果进行自洽计算,调查的干扰条件,数值。我们采用成功的4 $^{th}$阶网格技术,以获得实际的静电量的样品中使用的量子霍尔基于Aharonov-Bohm干涉仪。在已知电子密度分布的情况下,我们计算了边缘态的空间分布,这些边缘态被认为是单能电流通道。我们的计算结果与有关电子密度分布的实验结果一致。最后,我们还评论了“优化”的样品设计,其中最高的可见度振荡可以测量。

英文摘要:

Here, we report on our results where self-consistent calculations are performed to investigate the interference conditions, numerically. We employ the successful 4$^{th}$ order grid technique to obtain the actual electrostatic quantities of the samples used at the quantum Hall based Aharonov-Bohm interferometers. By knowing the electron density distribution we calculate the spatial distribution of the edge-states, which are considered as mono-energetic current channels. Our results are in accord with the experimental findings concerning the electron density distribution. Finally, we also comment on the "optimized" sample design in which highest visibility oscillations can be measured.
