Halide Double Perovskite Ferroelectrics
Angewandte Chemie, 2020 AbstractHalide double perovskites have recently emerged as a promising environmentally friendly optoelectronic and photovoltaic material for their inherent thermodynamic stability, high defect tolerance, and appropriate band gaps. However, to date, no ferroelectric material based on halide double perovskites has been discovered.

Shear-induced material transfer across the core-mantle boundary aided by the post-perovskite phase transition [PDF]
, 2005 We present a novel mechanical model for the extraction of outer core material upwards across the CMB into the mantle side region of D" and subsequent interaction with the post-perovskite (ppv) phase transition.

Layered Double Perovskites [PDF]
Annual Review of Materials Research, 2021 Successful strategies for the design of crystalline materials with useful function are frequently based on the systematic tuning of chemical composition within a given structural family. Perovskites with the formula ABX3, perhaps the best-known example of such a family, have a vast range of elements on A, B, and X sites, which are associated with a ...
