Depth resolved lattice-charge coupling in epitaxial BiFeO3 thin film [PDF]

, 2016
For epitaxial films, a critical thickness (t(c)) can create a phenomenological interface between a strained bottom layer and a relaxed top layer. Here, we present an experimental report of how the t(c) in BiFeO3 thin films acts as a boundary to determine

KDP:Mn piezoelectric coefficients obtained by X-ray diffraction

Journal of Synchrotron Radiation, 2010
Crystals of pure potassium dihydrogen phosphate KH(2)PO(4) (KDP) and Mn-doped KDP (KDP:Mn) were grown from a water solution by the slow evaporation method and their piezoelectric properties were studied by X-ray diffraction methods. The results have shown an increase in the piezoelectric coefficients with the doping.

Phonon-Coupled Electron Tunneling in Two and Three-Dimensional Tunneling Configurations

, 1999
We treat a tunneling electron coupled to acoustical phonons through a realistic electron phonon interaction: deformation potential and piezoelectric, in two or three-dimensional tunneling configurations.
