Graphene-like nanoribbons periodically embedded with four- and eight-membered rings

Embedding non-hexagonal rings into sp2-hybridized carbon networks is considered a promising strategy to enrich the family of low-dimensional graphenic structures. However, non-hexagonal rings are energetically unstable compared to the hexagonal counterparts, making it challenging to embed non-hexagonal rings into carbon-based nanostructures in a controllable manner. Here, we report an on-surfac...

Topological phase-diagram of time-periodically rippled zigzag graphene nanoribbons

The topological properties of electronic edge states in time-periodically driven spatially-periodic corrugated zigzag graphene nanoribbons are studied. An effective one-dimensionalHamiltonian is used to describe the electronic properties of graphene and the time-dependence is studiedwithin the Floquet formalism. Then the quasienergy spectrumof the evolution operator is obtained using analytical...
