摘要

摘要研究了能隙具有微弱周期性调制的半狄拉克晶体。研究了将此类晶体置于量子化磁场中时，晶体中迷你带的形成。研究表明，形成的磁性迷你带的宽度不仅取决于磁场强度，还取决于初始样品的带隙，这与间隙石墨烯形成了鲜明对比。研究还探讨了这一特征对所研究材料磁导率的影响。

Magnetic Minibands in Superlattices Based on the Semi-Dirac Crystals

Abstract

Semi-Dirac crystals with a weak periodic modulation of the energy gap has been considered. The formation of minibands in such crystals has been studied when the latter are placed in a quantizing magnetic field. The width of the formed magnetic minibands has been shown to depend not only on the magnetic field intensity, but also on the band gap of the initial sample in contrast to gap graphene. The effect of this feature on the magneto conductivity of studied material has been investigated.
