A team of physicists and chemists has produced the first porous graphene ribbons in which specific carbon atoms in the crystal lattice are replaced with nitrogen atoms. These ribbons have semiconducting properties that make them attractive for app<\/a>lications in electronics and quantum computing, as reported by researchers from the Universities of Basel, Bern, Lancaster and Warwick in the Journal of the American Chemical Society<\/i>.<\/p>\n

\n <\/section>\n

Graphene consists of a single layer of carbon atoms arranged in a honeycomb structure. The material is of interest not only in basic research but also for various applications given its unique properties, which include excellent electrical conductivity as well as astonishing strength and rigidity. Research teams around the world are working to further expand these characteristics by substituting carbon atoms in the crystal lattice with atoms of different elements. Moreover, electric and magnetic properties can also be modified by the formation of pores in the lattice.<\/p>\n

Ladder-like structure<\/b>
\nNow, a team of researchers led by the physicist Professor Ernst Meyer of the University of Basel and the chemist Dr. Shi-Xia Liu from the University of Bern have succeeded in producing the first graphene ribbons whose crystal lattice contains both periodic pores and a regular pattern of nitrogen atoms. The structure of this new material resembles a ladder, with each rung containing two atoms of nitrogen.
\nIn order to synthesize these porous, nitrogen-containing graphene ribbons, the researchers heated the individual building blocks step by step on a silver surface in a vacuum. The ribbons are formed at temperatures up to 220\u00b0C. Atomic force microscopy allowed the researchers not only to monitor the individual steps in the synthesis, but also to confirm the perfect ladder structure\u2014and stability\u2014of the molecule.
\nExtraordinary properties<\/b>
\nUsing scanning tunneling microscopy, the scientists from the Department of Physics and the Swiss Nanoscience<\/a> Institute (SNI) at the University of Basel also demonstrated that these new graphene ribbons were no longer electrical conductors, like pure graphene, but actually behaved as semiconductors. Colleagues from the Universities of Bern and Warwick confirmed these findings by performing theoretical calculations of the electronic properties. “The semiconducting properties are essential for the potential applications in electronics, as their conductivity can be adjusted specifically,” says Dr. R\u00e9my Pawlak, first author of the study.
\nFrom the literature, it is known that a high concentration of nitrogen atoms in the crystal lattice causes graphene ribbons to magnetize when subjected to a magnetic field. “We expect these porous, nitrogen-doped graphene ribbons to display extraordinary magnetic properties,” says Ernst Meyer. “In the future, the ribbons could therefore be of interest for applications in quantum computing.”<\/p>\n
