Controlled quantum dot formation in atomically engineered graphene nanoribbons field-effect transistors
Maria El Abbassi, Mickael Perrin, Gabriela Borin Barin +12
Graphene nanoribbons (GNRs) have attracted a strong interest from researchers worldwide, as they constitute an emerging class of quantum-designed materials. The major challenges to…
A Universal Length-Dependent Vibrational Mode in Graphene Nanoribbons
Jan Overbeck, Gabriela Borin Barin, Colin Daniels +13
Graphene nanoribbons (GNRs) have attracted considerable interest as their atomically tunable structure makes them promising candidates for future electronic devices. However, obtai…
Band Gap of Atomically Precise Graphene Nanoribbons as a Function of Ribbon Length and Termination
Leopold Talirz, Hajo Söde, Shigeki Kawai +7
We study the band gap of finite armchair graphene nanoribbons (7-AGNRs) on Au(111) through scanning tunneling microscopy/spectroscopy combined with density functional theor…
Structure-dependent electrical properties of graphene nanoribbon devices with graphene electrodes
Leonardo Martini, Zongping Chen, Neeraj Mishra +9
Graphene nanoribbons (GNRs) are a novel and intriguing class of materials in the field of nanoelectronics, since their properties, solely defined by their width and edge type, are…
Graphene Nanoribbons on Hexagonal Boron Nitride: Deposition and Transport Characterization
Tobias Preis, Christian Kick, Andreas Lex +7
Chemically synthesized "cove"-type graphene nanoribbons (cGNRs) of different widths were brought into dispersion and drop-cast onto exfoliated hexagonal boron nitride (hBN) on a Si…
Charge transport mechanism in networks of armchair graphene nanoribbons
Nils Richter, Zongping Chen, Alexander Tries +6
In graphene nanoribbons (GNRs), the lateral confinement of charge carriers opens a band gap, the key feature to enable novel graphene-based electronics. Successful synthesis of GNR…
