Hydrogen Species Motion in Piezoelectrics: A Quasi-Elastic Neutron Scattering Study



K. J. Alvine, Madhu Sudan Tyagi, Craig Brown, Terrence J. Udovic, T. Jenkins, S. G. Pitman


Hydrogen is known to damage or degrade piezoelectric materials, at low pressure for ferroelectric random access memory applications, and at high pressure for hydrogen powered vehicle applications. The piezoelectric degradation is in part governed by the motion of hydrogen species within the piezoelectric materials. We present here quasi-elastic neutron scattering (QENS0 measurements of the local hydrogen species motion within lead zirconate titanate (PZT) and barium titanate (BTO) on samples charged by gaseous exposure to high-pressure gaseous hydrogen (approxamitely equal to} 17 MPa). Neutron vibrational spectroscopy (NVS) studies of the hydrogen enhanced vibrational modes are presented as well. Results are discussed in context of theortically predicted interstitial hydrogen lattice sites and compared to comparable bulk diffusion studies of hydrogen diffusion in lead zirconate titanate.
