Macroscopic and local piezoelectric properties of Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals exhibiting giant piezoelectric response

Abstract

The temperature and bias field dependences of macroscopic, measured by pulsating load method, and local, measured by piezoresponse force microscopy, longitudinal piezoelectric responses have been studied in (001)

Giant piezoelectric properties of BZT–0.5BCT thin films induced by nanodomain structure

“…Lead-based compounds (PZT, PMN-PT), 1,2 which have been extensively applied in sensors, actuators, and energy harvesters, 3 are the most popularly used piezoelectric materials, due to their excellent piezoelectric properties. However, their wide application has caused many environmental problems because of the high toxicity of the high lead content in these piezoelectric materials.…”

First-principles studies of the local structure and relaxor behavior of Pb(Mg1/3Nb2/3)OTan1, Takenaka2, Xu3 et al. 2018Phys. Rev. B19390View full textAdd to dashboardCite

“…This has led to the intense interest in these materials. While many experimental investigations have focused on the dielectric dispersion and piezoelectric properties [9][10][11][12][13][14], the connection of composition and relaxor behavior is still not fully understood, even though it is known that heterovalency or a degree of disorder on the B-site is essential. However, by capturing the key features of the local atomic environment, our previous studies [15][16][17][18][19][20][21][22] using both density functional theory (DFT) and molecular dynamics (MD) have shed light on the relationship between the local structure and the relaxor behavior, as well as on the dynamics of relaxors.…”

Nanoscale mapping of heterogeneity of the polarization reversal in lead-free relaxor–ferroelectric ceramic composites

“…The average polarization switching behavior of the studied samples (compositional diversity) reveals a gradual evolution from tilted, slim hysteresis loops typical for the ergodic relaxors 35 to those with large hysteresis and a high piezoresponse characteristic for the samples with increased BNT-7BT content (Fig. 2).…”
