G. I. Rashba

摘要:

研究了磁场中纳米管表面孤立杂质原子场中电子的局域化问题。一个模型的高斯可分离的杂质势能够定位在任何强度的电子。地方层面的位置被发现在制度的强和弱本地化。找到了共振的位置,估计了共振的宽度。当管中的磁通量改变时,它们经历Aharonov-Bohm振荡。它示出的共振的位置经历类似的de Haas-van Alphen振荡,这是不相关的磁场的振荡。

英文摘要:

The localization of electrons in the field of isolated nonmagnetic impurity atoms on the surface of a nanotube in a magnetic field is considered. A model of a Gaussian separable impurity potential capable of localizing an electron at any intensity is used. The positions of the local level are found in the regime of strong and weak localizations. The positions of the resonances are found, their widths are estimated. They experience Aharonov-Bohm oscillations when the magnetic flux in the tube changes. It is shown that the positions of the resonances experience oscillations similar to the de Haas-van Alphen oscillations, which are not associated with a magnetic field.
