Quasiclassical calculations of the effective cyclotron mass and the spectrum of Landau levels have been carried out for carriers of the size-quantized H2 subband with a nonmonotonic dispersion law, which forms a valence band of 20.5-nm-wide HgTe quantum well with an inverted band structure. The model of the so-called “extremum loop”, previously developed by Rashba and Sheka for semiconductors with a wurtzite lattice, has been used for calculations. The results obtained are compared both with the empirical picture and with quantum-mechanical calculations of the Landau level spectrum for the HgTe quantum well in the semimetallic phase.

20.5nm宽的H gTe量子阱的Landau能级谱的准经典计算：“极值环”模型和立方对称性的影响

已经对具有非单调弥散定律的尺寸量化的H2子带的载流子进行了有效回旋加速器质量和Landau能级谱的准经典计算，该载流子形成了20.5 nm宽的HgTe量子阱的价带，并具有倒带。结构体。Rashba和Sheka先前针对具有纤锌矿晶格的半导体开发的所谓“极值回路”模型已用于计算。将获得的结果与经验图片以及半金属相中HgTe量子阱的Landau能级谱的量子力学计算进行了比较。
