High-field conduction in barium titanate [PDF]

Applied Physics Letters, 2005
We present current–voltage studies of very thin (∼77nm) barium titanate single crystals up to 1.3GV∕m applied field. These show that the mechanism of leakage current at high fields is that of space charge limited conduction (SCLC) in a regime with a continuous distribution of traps, according to the original model of Rose [Phys. Rev.

Dislocation‐Enhanced Pyroelectricity in Barium Titanate [PDF]

Advanced Materials
ABSTRACT Pyroelectric materials hold significant promise for thermal sensing, imaging, and energy harvesting, with the pyroelectric coefficient serving as the key figure of merit. While intrinsic lattice optimization, particularly through zero‐dimensional point defects, has improved pyroelectric properties ...

Synthesis of barium-zinc-titanate ceramics [PDF]

Science of Sintering, 2012
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered at 1250?C for 2h with a heating rate of 10?C/min. X-ray diffraction analysis of obtained powders and sintered samples was
