Vacancy-Engineered Flat-Band Superconductivity in Holey Graphene
Matheus S. M. de Sousa, Fujun Liu, Fanyao Qu +1
A bipartite lattice with chiral symmetry is known to host zero energy flat bands if the numbers of the two sublattices are different. We demonstrate that this mechanism of producin…
Symmetry-enforced nodal lines in the band structures of vacancy-engineered graphene
Matheus S. M. de Sousa, Fujun Liu, Mariana Malard +2
We elaborate that single-layer graphene with periodic vacancies can have a band structure containing nodal lines or nodal loops, opening the possibility of graphene-based electroni…
Less is more: Vacancy-engineered nodal-line semimetals
Fujun Liu, Fanyao Qu, Igor Zutic +1
A nodal-line semimetal phase which is enforced by the symmetries of the material is interesting from fundamental and application standpoints. We demonstrate that such a phase of ma…
