摘要:

本文利用非线性磁输运的平衡方程方法研究了高迁移率二维电子系统中的电流感生磁电阻振荡。在重叠朗道能级区,在高填充因子的微分磁阻的解析表达式,这表明与实验观察和数值计算,可能有助于从实验中提取的物理信息。

英文摘要:

We examine the current-induced magnetoresistance oscillations in high-mobility two-dimensional electron systems using the balance-equation scheme for nonlinear magnetotransort. The reported analytical expressions for differential magnetoresistivity at high filling factors in the overlapping Landau-level regime, which show good agreement with the experimental observation and the numerical calculation, may be helpful in extracting physical information from experiments.
