Two-dimensional superconductivity of the Ca-intercalated graphene on SiC: vital role of the interface between monolayer graphene and the substrate
Haruko Toyama, Ryota Akiyama, Satoru Ichinokura +10
Ca-intercalation has opened a way for superconductivity in graphene on SiC. However, the atomic and electronic structures being critical for superconductivity are still under discu…
Van Hove Singularity and Lifshitz Transition in Thickness-Controlled Li-Intercalated Graphene
S. Ichinokura, M. Toyoda, M. Hashizume +8
We demonstrate a new method to control the Fermi level around the van Hove singularity (VHS) in Li-intercalated graphene on the SiC substrate. By angle-resolved photoemission spect…
Soft-magnetic skyrmions induced by surface-state coupling in an intrinsic ferromagnetic topological insulator sandwich structure
Takuya Takashiro, Ryota Akiyama, Ivan A. Kibirev +11
A magnetic skyrmion induced on a ferromagnetic topological insulator (TI) is a real-space manifestation of the chiral spin texture in the momentum space, and can be a carrier for i…
