Finally, abrasive wear stops and the wear resistance of such a material increases by several orders of magnitude if the hardness of the material exceeds the hardness of the abrasive.
When a material with such a structure is worn, only elastic deformation takes place.

For the physical mechanism of the dielectric relaxation, it was found that the effect of grain sizes for the high-k materials’ structure mainly originates from higher surface stress in smaller grain due to its higher concentration of grain boundary.
Introduction Oxide materials with larger dielectric constants (so-called high-k dielectrics) than 3.9 (SiO2’s dielectric constant) have attracted much attention due to their potential use as gate dielectrics in MOSFETs to overcome the gate leakage problem [1].
