Negative Piezoelectric Coefficient in Ferromagnetic 1H-LaBr2 Monolayer. [PDF]

open access: yesACS Appl Electron Mater, 2022
The discovery of two-dimensional (2D) magnetic materials that have excellent piezoelectric response is promising for nanoscale multifunctional piezoelectric or spintronic devices. Piezoelectricity requires a noncentrosymmetric structure with an electronic band gap, whereas magnetism demands broken time-reversal symmetry.

Unconventional piezoelectric coefficients in perovskite piezoelectric ceramics

open access: yesJournal of Materiomics, 2021
Piezoelectric ceramics exhibit three conventional piezoelectric coefficients, i.e., d33, d31, d15, due to their ∞mm crystal symmetry. Unconventional piezoelectric coefficients, such as d11, d12, d13, d14, d16, etc., can only be extracted from piezoelectric single crystals of special symmetry with specific cut direction.
