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 magnetoconductivity of studied material has been investigated.
