E. V. Deviatov, A. Lorke, G. Biasiol, L. Sorba

摘要:

我们使用一种新的样品几何结构来研究整数量子霍尔效应中边缘激发的非局域效应。我们发现,量子霍尔边缘的局域平衡条件受到动态极化核扩散的影响。我们的分析表明,在本实验中,核扩散是有效的一维。

英文摘要:

We use a novel sample geometry to study non-local effects of edge excitations in the integer quantum Hall effect regime. We find that the condition of local equilibrium at the quantum Hall edge is affected by the diffusion of dynamically polarized nuclei. Our analysis indicates, that the nuclear diffusion is effectively one-dimensional in the present experiment.
