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…
On-surface synthesis of polyazulene with 2,6-connectivity
Qiang Sun, Ian Cheng-Yi Hou, Kristjan Eimre +4
Azulene, the smallest neutral nonalternant aromatic hydrocarbon, serves as not only a prototype for fundamental studies but also a versatile building block for functional materials…
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…
On-surface synthesis of antiaromatic and open-shell indeno[2,1-b]fluorene polymers and their lateral fusion into porous ribbons
Marco Di Giovannantonio, Kristjan Eimre, Aliaksandr V. Yakutovich +8
Polycyclic hydrocarbons have received great attention due to their potential role in organic electronics and, for open-shell systems with unpaired electron densities, in spintronic…
Optimized substrates and measurement approaches for Raman spectroscopy of graphene nanoribbons
Jan Overbeck, Gabriela Borin Barin, Colin Daniels +13
The on-surface synthesis of graphene nanoribbons (GNRs) allows for the fabrication of atomically precise narrow GNRs. Despite their exceptional properties which can be tuned by rib…
