Description
Zigzag graphene nanoribbons (ZGNRs) have attracted considerable interest due to the unique edge states they host. We recently established an on-surface synthesis approach to synthesize atomically precise 6-ZGNRs using a carefully designed precursor monomer. Furthermore, our recent experiments on exfoliated graphene nano-constrictions provide the first evidence through ballistic electron transport measurements that the edge states are spin polarized. To exploit these properties in devices we need to have ZGNRs on suitable substrates, this has been not yet achieved as the ZGNRs are extremely reactive. With the goal of passivating these edges in UHV to facilitate their transfer to ambient conditions, we present first results of how morphology and electronic properties of 6-ZGNRs change when exposed to reactive gases.
