Stacking-dependent topological electronic structures in honeycomb-kagome heterolayers
Chan Bin Bark, Hanbyul Kim, Seik Pak +4
Heterostructures of stacked two-dimensional lattices have shown great promise for engineering novel material properties. As an archetypal example of such a system, the hexagon-shar…
