“…Delobelle examined the effect of surface roughness on mechanical properties of thin film and found that the more the disorientation of film was, the greater was the standard deviation of modulus at the same penetration depth [18]. This is in agreement with Wang's analysis [16].…”

“…Considering the anisotropy of PZT thin films, the indentation modulus is of more scientific and practical importance than Young's modulus in many cases [13]. Some groups have examined the effects of grain size and crystal preferred orientation on the mechanical properties of PZT thin films by nanoindentation technology [14][15][16][17][18]. However, these factors are usually combined together, which makes it difficult to obtain a coincident conclusion.…”

“…However, these factors are usually combined together, which makes it difficult to obtain a coincident conclusion. Moreover, several theoretical methods suited for bulk monocrystal materials have been used to evaluate the indentation modulus [10,18], elastic constants [19] and biaxial modulus [20,21] of fiber-textured films. To our knowledge, however, there have been no reports on the calculation of indentation modulus of PZT thin films using Voigt-Reuss-Hill (VRH) model considered an excellent theoretical estimation [21].…”

“…Although nanoindentation has been widely used to characterize the mechanical properties of PZT ceramics [9][10][11][12][13][14][15][16], as well as single crystal materials [17][18][19][20][21][22][23], few studies relating to this issue have been reported on single crystal PZN-PTs [8].…”

The deformation behavior of [001] T -and [011] T -cut single crystal solid solution of Pb(Zn 1/3 Nb 2/3 )O 3 -6% PbTiO 3 (PZN-6%PT) in both unpoled and poled states has been investigated by nanoindentation. Nanoindentation experiments reveal that material pile-up and local damage around the indentation impressions are observed at ultra-low loads. These pile-ups and local damage cause a pop-in event (i.e. a sudden increase in displacement at an approximately constant load) in the nanoindentation load-displacement curve (P-h curve). Detailed studies of the relationships between indentation load (P), displacement (h) and harmonic contact stiffness (S ) suggest that there is a surface layer, possibly due to crystal fabrication processes, which possesses different mechanical properties from the interior. The thickness of this surface layer is estimated to be approximately 300 nm. Furthermore, it is found that [011] T -cut crystal is stiffer than [001] T -cut crystal. On the other hand, both [001] T -and [011] T -cut crystals in unpoled state possess lower contact stiffness than poled crystals. This finding suggests that poling improved the mechanical property of the crystal. In summary, poled [001] T -cut crystals have an elastic modulus of (107 AE 6) GPa and a hardness of (5.1 AE 0.4) GPa. In contrast, the modulus for [011] T -cut crystals is not constant but increases with indentation depth.

“…The residual stress in films has important effects on the properties, performance and long term stability of the films [5], leading for a need for better understanding of mechanical properties of films. A range of methods is currently available to estimate residual stresses such as neutron diffraction [6], nano-indentation [7], X-ray diffraction [8] and Raman spectroscopy [9].…”
