Advanced Theory and Simulations, Volume 6, Issue 12, December 2023., 2023 A model is presented for birefringent scattering that is applicable to any single‐phase, unaligned transparent polycrystal. The model can treat grain size distributions and is not limited to a specific material system. The derivation culminates in an equation that describes birefringence scattering coefficient spectra using the single‐crystal ...

Acoustic properties of piezoelectric cubic crystals
International Journal of Ceramic Engineering &Science, Volume 5, Issue 5, September 2023., 2023 Abstract This paper is offered as a complementary adjunct to the many treatments of the electronic and photonic properties of cubic III–V and II–VI compounds appearing in the literature. These crystals typically exhibit piezoelectricity, due to the molecular dissymmetry, thereby allowing the inclusion of classical mechanical/acoustic features along ...

Advanced Materials, Volume 34, Issue 7, February 17, 2022., 2022 In domain‐engineered relaxor ferroelectric crystals of Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3, reversible and repeatable phase transitions from the as‐poled polydomain rhombohedral state to a monodomain monoclinic state can be stimulated by electric field or stress. These transitions lead to bimodal functionality—variable optical transparency as well
