Valley-driven Zitterbewegung in Kekulé-distorted graphene
Alex Santacruz, Priscilla E. Iglesias, Ramon Carrillo-Bastos +1
Graphene deposited on top of a Copper(111) substrate may develop a Y-shaped Kekulé bond texture (Kekulé-Y), locking the momentum of its Dirac fermions with its valley degree of fre…

Electronic spectrum of Kekule patterned graphene considering second neighbor-interactions
Elias Andrade, Gerardo G. Naumis, Ramon Carrillo-Bastos
The effects of second-neighbor interactions in Kekule patterned graphene electronic properties are studied starting from a tight-binding Hamiltonian. Thereafter, a low-energy effec…
