Two-dimensionality of metallic surface conduction in Co3Sn2S2 thin films

[摘要] Magnetic Weyl semimetals, such as Co₃Sn₂S₂, are ideal to realise anomalous transport properties based on the Berry curvature in the specific electronic bands and are expected to be useful for topological spintronics. Here, the authors investigate the bulk and surface conduction channels of Co₃Sn₂S₂ determining the relationship between the film thickness and surface conductance.
