非平面SiGe/Si纳米膜中的磁输运
Magnetotransport in non-planar SiGe/Si nanomembranes
摘要：
研究了在磁场作用下非平面SiGe/Si谐振量子腔（RQC）中电子学与几何结构的关系。转移矩阵技术最初是由于Replanki和同事（物理修订版B 52，8244 1995年）已被修改，占非零的局部曲率的RQC。我们的研究结果表明，在非平面RQC的低温弹道磁导是高度敏感的曲率的变化范围广泛的磁场强度。
英文摘要：
We investigate the relationship between electronics and geometry in a nonplanar SiGe/Si resonant quantum cavity (RQC) subject to a magnetic field. The transfer matrix technique originally due to Usuki and coworkers (Phys. Rev. B 52, 8244 1995) has been modified to account for the nonzero local curvature of the RQC. Our results demonstrate that low-temperature ballistic magnetoconductance in nonplanar RQCs is highly sensitive to the changes in curvature for a wide range of magnetic field strengths.
