Research paperTheoreticalComputationalIntravalley Andreev reflection in the multi-terminal device with Y-shaped Kekulé graphene superlatticesChao Wang, Peipei Zhang, Yu-Xian Li, Juntao SongarXiv·2024·10.2139/ssrn.5002438·arXiv:2404.09407AbstractUsing a tight-binding model and nonequilibrium Green’s function method, the paper studies Andreev reflection in multi-terminal graphene-superconductor devices with either pristine graphene or Y-shaped Kekulé graphene superlattice central regions. It shows that intervalley and intravalley Andreev reflection can be tuned by the central-region structure and the superconductor phase difference, and that Kekulé coupling can enhance intravalley Andreev reflection in crossed processes.Read more
