Graphene Nanoribbons
This work studies the growth, characterization, and device integration of 5‐armchair graphene nanoribbons (GNRs). 5‐AGNRs are synthesized under ultrahigh vacuum conditions from Br‐ and I‐substituted precursors. In article number 2202301, Gabriela Borin Barin, Pascal Ruffieux, and co‐workers show that I‐substituted precursors and optimized initial precursor coverage quintuple the...
The electronic, optical, and magnetic properties of graphene nanoribbons (GNRs) can be engineered by controlling their edge structure and width with atomic precision through bottom‐up fabrication based on molecular precursors. This approach offers a unique platform for all‐carbon electronic devices but requires careful optimization of the growth conditions to match structural requirements for successful...
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 ribbon width and edge structure, significant challenges remain for GNR processing and characterization. Herein, Raman spectroscopy is used to characterize different types of GNRs on their growth substrate and track their quality...
On‐surface synthesized N = 9‐armchair graphene nanoribbons (AGNRs) are investigated by Raman spectroscopy and AFM/micro photoluminescence measurements. In order to perform the optical experiments, the AGNR film is transferred on a glass substrate through a non‐membrane method. The Raman spectroscopy shows the radial breathing‐like mode characteristic of the 1D nature of GNRs, proving the efficiency...
