are quite sizeable, the effect of scattering would lead to a detrimental impact on the transport characteristics. However, the recent theoretical prediction of sublatticeasymmetry, a situation where dopants are distributed in one sublattice only, is expected to yield very low scattering transport
sublatticeasymmetry of N-graphene
The main focus of the work by Zhao et al. was the observation and characterization of nitrogen dopants via scanning tunnel spectroscopy (STS), followed by a short investigation on the transport properties of the resulting graphene. Their experimental observation of same
