Graphene nanoribbon
open-in-new
<p>Graphene nanoribbons (GNRs, also called nano-graphene ribbons or nano-graphite ribbons) are strips of <a href="/facts/Graphene/QDGUBaPt">graphene</a> with width less than 100 nm. Graphene ribbons were introduced as a theoretical model by <a href="/facts/Mitsutaka_Fujita/C1vb1RSa">Mitsutaka Fujita</a> and coauthors to examine the edge and nanoscale size effect in graphene. Some earlier studies of graphitic ribbons within the area of conductive polymers in the field of synthetic metals include works by Kazuyoshi Tanaka, Tokio Yamabe and co-authors, <a href="/facts/Steven_Kivelson/bDdn6Qwf">Steven Kivelson</a> and Douglas J. Klein. While Tanaka, Yamabe and Kivelson studied so-called zigzag and armchair edges of graphite, Klein introduced a different edge geometry that is frequently referred to as a bearded edge. </p>
