“…For most cases, to image bare surfaces, a simulated tip bias voltage of ±0.1 V proved valuable at a constant current of ∼1.0 nA. In fact, rather similar conditions were used in STM experiments on NbC (001) and VC 0.8 (111), noting that a reversal of bias remained without a noticeable influence on image appearance, as we can affirm from simulated images in most cases. As expected, the TiC (001) bare surface then exhibits the expected ordered pattern with C (Ti) atoms appearing bright (dark).…”

“…The diagonal distance of the square lattice in the image is approximately 4.5 Å, which agrees well with the FCC unit-cell lattice constant of 4.506 Å determined by XRD. [24] On the basis of the conclusion of the early REED experiments, it is likely that the atomic-resolution STM image made the carbon lattice visible. [25] As illustrated above, we were able to expose two types of flat area, both suitable for STM experiments.…”

“…The regular ridge-and-valley structure of the substrates whose period is as small as 10 nm is also formed spontaneously to reduce the total surface energy on annealing. The faceted surface structures with even smaller period have been reported for NaCl type transition-metal carbides, e.g., TaC [2,3], HfC [4], and NbC [5].…”
