|Title:||Piezoelectric coefficients of mNA organic nonlinear optical material using synchrotron X-ray multiple diffraction|
|Abstract:||Distortions produced in the unit cell of a nonlinear organic crystal under the influence of an applied electric field E are investigated by using synchrotron x-ray multiple diffraction (MD). A typical MD pattern shows numerous (hkl) secondary peaks and the position of each one is basically a function of the unit cell lattice parameters. Thus small changes in any parameter due to a strain produced by E give rise to a corresponding variation in the (hkl) peak position. The method was applied to the meta-nitroaniline (mNA) crystal and we were able to determine three piezoelectric coefficients. [S0031-9007(98)07912-5].|
