The electronic properties of graphene have, since the discovery of the material in 2004, been greatly investigated. Especially the promise for a next generation of electronic components has led to research being done that aims to manipulate these properties.  One of the goals has been to create a bandgap in the usually gapless material without diminishing the high level of conduction usually found. Recently, it was discovered that it is possible to break the usual sublattice symmetry by substitutional doping, and furthermore that this leads to a bandgap forming. Our investigation [1] is a general theoretical study on graphene nanoribbons doped in this manner, and it shows, amongst others, large edge dependence and high conducting channels forming.
