Description
Nicolò Bassi and co-authors grow graphene ribbons with nitrogen set in a chosen seat in the ribbon. The ribbons are one-atom-thick strips whose electronic traits bend with width and with doped atoms. Where a doped atom sits shapes its effect, so seat choice is the whole game. Their 2024 study grows the ribbons on a gold surface, with ring parts that add nitrogen at the edge.
Fine probes backed the target build. In more than 90 percent of units, growth chose the bond that puts nitrogen in the prized seat. Math models of the growth path show why that bond wins. Electronic readings found the ribbons act like a metal on gold, with charge passed from the base. States tied to the nitrogen showed too. The work guides doped ribbon design.
