Patterning Graphene Through the Self-assembled Templates: Toward Periodic Two-dimensional Graphene Nanostructures with Semiconductor Properties

Periodic graphene nanostructures are fabricated via patterning graphene through the self-assembled monolayers of monodisperse colloidal microspheres. The resulting structures exhibit promising electronic properties featuring high conductivities and ON-OFF ratios up to 10. The apparent advantages of the presented method are the possibilities of fabricating periodic graphene nanostructures with different periodicities, ranging from ∼100 nm to several μm, and also varying the periodicity and the neck width independently. The use of the presented method yields graphene nanostructures with variable electronic properties.
