Magneto-Electronic Energy Spectra of Monolayer Tinene

The novel magnetic quantization in monolayer tinene, being closely related to the sp$^{\mathrm{3}}$ bondings, spin-orbital coupling and magnetic field, is investigated by the generalized tight-binding model. The feature-rich two groups of low-lying LLs, which are, respectively, dominated by the 2p$_{\mathrm{z}}$ orbitals and (2p$_{\mathrm{x}}$,2p$_{\mathrm{y}})$ orbitals, are revealed near the Fermi level simultaneously. They are very different in the spatial distributions, state degeneracy, spin configurations and B$_{\mathrm{z}}$-dependence. The B$_{\mathrm{z}}$-dependent energy spectra might be approximated by the simple relationships. The splittings of LLs in the second groups are due the effects of magnetic fields. The unique magnetic-electronic properties in tinene are absent in graphene, silicene and germanene. The predicted magneto-electronic energy spectra could be directly verified by the STS measurements.
