PbTiO3 nanoplates were synthesized by a two-step hydrothermal method, and ammonia solution was chosen as pH-adjusting agent. The effect of concentration in the second-step precursors, Pb-Ti feedstock concentration, reaction temperature, time on crystallization morphologies nanocrystals investigated. typical single-crystal with stair-like edge formed, nominal first-step precursors 8.8 mol/L, 4.4...

Mn ions' doping site and valence were studied in PbTiO3 (PT) with the native vacancy defects by first-principles calculations. Firstly, of Pb, O Ti PT investigated it was found that Pb is preferred to others. And then growth doped should be ion substituting for an A-site +3 when deficient under equilibrium conditions driven solely minimization formation energy, this could result a larger lattic...

Thermal stabilities of relaxor-PbTiO3 single crystals are great importance due to their limited operational temperatures in devices. Herein, elucidate how poling conditions influence thermal stabilities, we investigated direct current (DC) and alternating (AC) poled Pb(Mg1/3Nb2/3)O3-0.29PbTiO3 (PMN-29PT) grown by solid-state crystal growth, which guarantees more compositional uniformity. Our ex...
