Bandgap engineering in graphene nanomesh for photovoltaics
Graphene, a flat monolayer of carbon atoms tightly packed into a two-dimensional honeycomb lattice, was first isolated in 2004. Graphene has attracted a great deal of research interest due to its many amazing properties, including its high electron transport speed which could be very useful for charge transfer in photovoltaic cells. Bulk graphene is a semimetal with zero bandgap, limiting its usages in electronic and optoelectronic devices. Graphene nanoribbons, structurally defected graphene, and other approaches have been proposed to open up a sizable bandgap, but none of these are suitable ...
