Pb(ZrxTi1-x)O3 [PZT] thin films of morphotropic phase boundary (MPB) composition having {001}, {110}, and {111}orientations were fabricated on silicon substrates (111)Pt/Ti/SiO2/Si using a metal organic decomposition spin-coating technique. The influence of crystallographic orientation on the transverse piezoelectric coefficient e31 * of the films have been determined. The largest e31 * was fou...

We consider a curve α = α(s) in Minkowski 3-space E31 and denote by {T,N,B} the Frenet frame of α. We say that α is a slant helix if there exists a fixed direction U of E31 such that the function 〈N(s), U〉 is constant. In this work we give characterizations of slant helices in terms of the curvature and torsion of α. MSC: 53C40, 53C50

Salkowski [11], one century ago, introduced a family of curves with constant curvature but non-constant torsion (Salkowski curves) and a family of curves with constant torsion but non-constant curvature (anti-Salkowski curves) in Euclidean 3-space E. In this paper, we adapt definition of such curves to time-like curves in Minkowski 3-space E31. Thereafter, we introduce an explicit parametrizati...

Herein, the systematic change in self-polarization behavior against post-heat treatment after film deposition was investigated to understand origin of hydrothermally prepared (KxNa1−x)NbO3 films with x = 0.88 at 240 °C below Curie temperature. The transverse piezoelectric constant, e31,f, evaluated by cantilever method. as-prepared and heat-treated 300 had an almost perfectly self-polarized sta...
