Open AccessSmall bandgap in atomically precise 17-atom-wide armchair-edged graphene nanoribbons
Bottom-up synthesis of graphene nanoribbons (GNRs) may open new possibilities in future electronic devices owing to their tunable electronic structure, which depends strongly on their well-defined width and ed...

Visualization of Covalent Bonding between NO Molecules on Cu(110)
Using STM at 6 K, the valence states of NO molecules adsorbed monomerically on Cu(110) upon deposition at about 15 K were investigated. The NO monomer was found to be bonded at the short-bridge site in an upri...

Introduction
Nitric oxide (NO or nitrogen monoxide) is a diatomic molecule consisting of a nitrogen atom and an oxygen atom. It is a free radical, i.e., a relatively stable molecule with an unpaired electron. Owing to its ...
