Perovskite lead-free piezoelectric ceramics [PDF]

Journal of Applied Physics, 2020
The ability of piezoelectric devices to convert mechanical energy to electrical energy and vice versa has inspired remarkable growth in research on piezoelectric materials. However, based on the Restriction of Hazardous Substances legislation, it is necessary to eliminate the lead from currently used piezoelectric ceramics. Together with the increasing

A novel dimethylformamide (DMF) free bar-cast method to deposit organolead perovskite thin films with improved stability [PDF]

, 2016
We report a solvent-free approach to synthesizing organolead perovskites by using solid state reactions to coat perovskite crystals onto Al2O3 or TiO2 nanoparticles followed by addition of terpineol affording perovskite inks.

Ag/In lead‐free double perovskites [PDF]

EcoMat, 2020
AbstractLead‐free Cs2AgInCl6 and Cs2AgInBr6 double perovskites are studied by a combination of advanced ab‐initio calculations and photoluminescence experiments. We show that they are insulators with direct band gaps of 2.53 and 1.17 eV, respectively; most importantly, they are characterized by unusually low absorption rates in a ~1 eV wide energy ...
