The electronic properties of Co nanowires on Cu(110)-p(2 × 3)N

► We grow quasi one-dimensional Co nanowires on the Cu(110)-p(2 × 3)N (Cu3N) surface. ► We perform scanning tunneling spectroscopy measurements at 7 K on these wires. ► We present the first study of the electronic properties of Co wires grown on top of Cu3N. ► Spectroscopic features measured on the Co wires and on Cu3N show striking similarities.
