Abstract: Abstract Thermally-stable (0.75-x)BiFeO3-0.25PbTiO3-xBa(Zr0.25Ti0.75)O3 (0.1 ≤ x ≤ 0.27) piezoelectric ceramics were reported to have excellent dielectric and electromechanical properties of d33∼405 pC/N, kp∼46%, e33T/e0∼1810, tanδ∼3.1% and Tc∼421 °C close to tetragonal (T)-rhombohedral (R) morphotropic phase boundary. The dielectric measurement indicates… read more here.

Abstract: Abstract The combination of materials with large lattice mismatch due to different phase structures plays a significant role on designing devices. Precise control of heteroepitaxial thin films is still a big challenge because of the… read more here.

DOI: 10.1039/c9tc05395f
Abstract: Using detailed first-principles calculations, we investigated the behaviour of interface vacancies in a lateral heterostructure (LHS) constructed by arsenene (As) and antimonene (Sb), which has been demonstrated to have many unique properties but with a… read more here.
