摘要
We find that an atomically thin MoS2 monolayer with squared pentagon structure motifs, distinct from all the conventional MoS2 monolayers, has unique electronic band structures with Dirac cones comprising d orbitals. The squared pentagon MoS2 monolayer is an intrinsic ferromagnet with a high Curie temperature and behaves as a half semimetal, which possesses spin-polarized Dirac fermions around the Fermi level. Moreover, when spin-orbit couplings are included, the magnetic Dirac band is gapped, hosting quantized conductance channels. This work provides insights in achieving two-dimensional topological materials with unique atomistic patterns.
