We have previously reported a 1.36-nm DOS modulation in the CuO chains on the surface of cold-cleaved, atomically-resolved YBCO.1,2 We have recently completed new experiments in which we obtained detailed spectroscopic data on the same crystal plane, thereby confirming and extending our earlier work. Here we present data showing twin boundaries and steps, and focusing on the effects of these structures on the CuO chain DOS modulations.
