The Importance of Microstructure When Gauging the Efficacy of Pulse Poling in Perovskite Single Crystals

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT Perovskite PMN‐PZT single crystals grown via solid‐state crystal growth (SSCG) were subjected to the pulse poling process to boost piezoelectric performance. Pulse poling subjects samples to short pulses of electric field in rapid succession and has previously demonstrated vast property improvements in Bridgman‐grown single crystals by driving

Experimental methodology for the measurement of plasticity on metals at high strain-rates

EPJ Web of Conferences, 2018
An experimental methodology has been developed for the tensile characterisation of ductile isotropic metals at high strain-rate. This study includes the region beyond plastic instability or necking, which is rarely analysed for conventional applications.

X-ray scattering studies of compound semiconductors [PDF]

, 1997
In this thesis, techniques of high resolution x-ray diffraction, topography and grazing incidence reflectivity have been employed in order to gain information on compound semiconductors. A recent growth technique. Vertical Gradient Freeze (VGF), has been

Bridgman growth and site occupation in LuAG:Ce scintillator crystals [PDF]

, 2010
LuAG:Ce single crystals with various activator concentrations were grown by the vertical Bridgman technique. Characterization of crystals was done in terms of actual doping level, macroscopic defects and degree of non-equivalent substitutions by Lu for ...

High compositional homogeneity of CdTexSe1−x crystals grown by the Bridgman method

APL Materials, 2015
We obtained high-quality CdTexSe1−x (CdTeSe) crystals from ingots grown by the vertical Bridgman technique. The compositional uniformity of the ingots was evaluated by X-ray fluorescence at BNL’s National Synchrotron Light Source X27A beam line.
