Correlation between structural and mechanical properties of PbTiO3 thin films grown by pulsed-laser deposition

Mechanical properties of sol–gel derived lead zirconate titanate thin films by nanoindentation

“…Roemer also confirmed that the PbTiO 3 films with random orientations possessed rougher surfaces. As a result, the evolution of modulus and hardness was quite dispersed in terms of the lower crystalline quality of the film and its higher surface roughness [9]. This explains the greater standard deviations of indentation modulus and hardness for sample C with respect to its random orientation when compared with samples A and B (Fig.…”

“…Many researchers have employed this technique to investigate the mechanical properties of various kinds of thin films including some ferroelectric thin films [8][9][10]. It has been suggested that PZT thin films prepared by different methods usually have different textures or crystal preferred orientations [10][11][12] which affect the ferroelectric and mechanical performances of the films.…”

Deposition of PbTiO3 films on Pt/Si substrates using pulsed laser deposition

“…Kang reported the growth of c-axis oriented PbTiO 3 films on single crystal SrTiO 3 and MgO substrates at temperatures ranging from 550 • C to 700 • C. Other authors have also reported the growth of lead titanate thin films on MgO substrates. [16][17][18][19] Deveirman presented TEM and XRD characterization of lead titanate thin films grown by PLD on LaAlO 3 , SrTiO 3 , MgO, and MgAl 2 O 4 . Wu prepared lead titanate thin films on Si substrates employing CeO 2 and Y 2 O 3 buffer layers 20,21 while Purandare prepared oriented Si substituted lead titanate thin films by pulsed laser deposition on Si(1 0 0) substrates.…”

Effective biaxial modulus and strain energy density of ideally (hkl)-fiber-textured hexagonal, tetragonal and orthorhombic films

“…The specific microstructures of fiber texture or preferred orientation of polycrystalline thin films fabricated by many methods such as sputtering technology, pulsed-laser deposition and chemical vapor deposition [1][2][3], have attracted much attention from the research community. The out-of-plane orientations of all grains in the fiber-textured films are almost parallel to a specific crystallographic direction, while the in-plane orientations of the grains are nearly random [4].…”
