Ionic crystals are one of the least difficult constructions in nature. they are often simply cleaved in air and in vacuum, and the ensuing surfaces are atomically flat on parts 1000s of nanometers huge. With the advance of scanning probe microscopy, those surfaces became a terrific playground to enquire a number of phenomena taking place at the nanometer scale. This booklet makes a speciality of the elemental reports of atomically resolved imaging, nanopatterning, steel deposition, molecular self-assembling and nanotribological methods happening on ionic crystal surfaces. the following, an important number of constructions are created by way of nanolithography, annealing and irradiation through electrons, ions or photons, and are used to restrict steel debris and natural molecules or to enhance our easy knowing of friction and put on at the atomic scale. steel oxides with broad band hole also are mentioned. Altogether, the implications acquired to date can have an undoubted effect at the destiny improvement of nanoelectronics and nanomechanics.

A home-built AFM, optimized for friction measurements in UHV, is represented in Fig. 2. Fig. 1 Schematic view of an atomic force microscope (AFM). The inset shows the principle of operation in contact mode. The tip-sample force can be related not only to the static bending or torsion of the cantilever. In dynamic AFM techniques [Meyer et al. (2004)], the cantilever is excited in the vicinity of one of its resonance frequencies, and the tip-sample interaction is estimated from the oscillation amplitude or the shift of the resonance frequency.
A grid of rhombic unit cells was observed, with a high degree of order at the center of each unit cell and disordered regions at the boundaries between unit cells (Fig. 7). A hexagonal arrangement of atoms was found at the center of each rhombus (not shown here). The authors also noticed that the disordered areas at the boundaries of the rhombi were preferential locations for chemical reactions when the surface was exposed to water and hydrogen (Fig. 8). Although the exact nature of these reactions could not be determined, it is plausible that the reactions corresponded to the onset of hydroxide formation.
