Impurity invisibility in graphene: Symmetry guidelines for the design of efficient sensors
John Duffy, James A Lawlor, Caio Lewenkopf +1
Renowned for its sensitivity to detect the presence of numerous substances, graphene is an excellent chemical sensor. Unfortunately, which general features a dopant must have in or…

The influence of Gaussian strain on sublattice selectivity of impurities in graphene
James A Lawlor, Claudia G Rocha, Vanessa Torres +2
Among the different strategies used to induce the opening of a band gap in graphene, one common practice is through chemical doping. While a gap may me opened in this way, disorder…

Sublattice Segregation of Hydrogen Adsorbates in Carbon Nanotubes
James A. Lawlor, Mauro S. Ferreira
Recent experimental observations have reported that, rather than randomly distributed, nitrogen atoms may prefer to be located on one of the two sub-lattices of graphene. It has be…
