Abstract

We present the first measurements of the differential conductance of Co wires grown on top of Cu(110)-p(2 × 3)N (Cu ₃N). We apply scanning tunneling spectroscopy (STS) in constant height and constant current mode to access the electronic density of states of the sample over a wide energy range. All measurements have been performed at 7 K. Our study reveals that the differential conductance of the Co wires is very similar to that of Cu ₃N. Spectra of the differential conductance measured on the Co wires and on Cu ₃N reveal that both systems exhibit the same characteristic features near + 1.8V and + 3.5 V.
