In our experiments, we use silicon probes for NC-AFM employed in an active imaging technique, achieving the first single-atom resolution AFM images. As expected for the model calculated with DFT, the clean diamond (001) surface is stabilized in a reconstruction. The distance between the dimers has been carefully analyzed and will be discussed in the present. We also obtained high-resolution AFM images of dimer rows on clean diamond (001) surfaces. We anticipate the present results promote the future performance of diamond devices.
