研究了p型HgCdTe薄膜反型层中门控二维电子气(2DEG)的磁导。在强磁场下,观察到了单子带占据的二维电子气的量子霍尔效应等特征。在弱磁场下,在弹道区域观察到微弱的反局域化效应。相位相干时间和零场自旋分裂是根据戈卢布的模型[L.E.戈卢布,物理。修订本B 71,235310(2005年)]。退相率与温度的关系符合奈奎斯特机制。
Magnetoconductance of a gated two-dimensional electron gas (2DEG) in an inversion layer on a p-type HgCdTe film is investigated. At strong magnetic fields, characteristic features such as the quantum Hall effect of a 2DEG with single subband occupation are observed. At weak magnetic fields, the weak antilocalization effect in the ballistic regime is observed. Phase coherence time and zero-field spin-splitting are extracted following Golub’s model [L. E. Golub, Phys. Rev. B 71, 235310 (2005)]. The temperature dependence of the dephasing rate is consistent with the Nyquist mechanism.
