Graphene nanoribbons with incorporated Co atoms: Optical spectrum and magnetic response

Abstract

Graphene nanoribbons are attracting much attention as a platform for optoelectronics. Properties of graphene nanoribbons depend on the width, edge type, edge atoms, etc. and can be significantly changed. Inducing magnetism to graphene nanoribbons would open up a new field for applications. In this work we study optical and magnetic properties of graphene nanoribbons with cobalt incorporated atoms that were grown inside single-walled carbon nanotubes from cobalt phthalocyanine molecules.
