强面内磁场作用下准二维电子气的可公度振荡

Commensurability oscillations in a quasi-two-dimensional electron gas subjected to strong in-plane magnetic field

Ludvik Smrcka

摘要:

本文对受单向周期势调制的准二维电子气在强面内倾斜磁场作用下的可压缩性振荡进行了理论研究。由于有限宽量子阱中面内场分量和限制势的耦合,原本为圆形的回旋轨道变得各向异性并倾斜出样品平面。一个准经典的理论方法,涉及的磁阻振荡的指导中心漂移,扩展到这种情况下。

英文摘要:

We report on a theoretical study of the commensurability oscillations in a quasi-two-dimensional electron gas modulated by a unidirectional periodic potential and subjected to tilted magnetic fields with a strong in-plane component. As a result of coupling of the in-plane field component and the confining potential in the finite-width quantum well, the originally circular cyclotron orbits become anisotropic and tilted out of the sample plane. A quasi-classical approach to the theory, that relates the magneto-resistance oscillations to the guiding-center drift, is extended to this case.
