Russian researchers have proposed a new method for synthesizing high-quality graphene nanoribbons a material with potential for applications in flexible electronics, solar cells, LEDs, lasers, and more. Presented in
The Journal of Physical Chemistry C, the original approach to chemical vapor deposition, offers a higher yield at a lower cost, compared with the currently used nanoribbon self-assembly on noble metal substrates.
Silicon-based electronics are steadily approaching their limits, and one wonders which material could give our devices the next big push. Graphene, the 2D sheet of carbon atoms, comes to mind but for all its celebrated electronic properties, it does not have what it takes: Unlike silicon, graphene does not have the ability to switch between a conductive and a nonconductive state. This defining characteristic of semiconductors like silicon is crucial for creating transistors, which underlie all of electronics.
