Abstract
Piezoelectricity Experimental evidence and origin of the anion-dependent piezoelectricity in methylammonium lead halides MAPbX3 (X = I, Br, and Cl) thin films are proposed with excellent electromechanical power-generating capability of 23.1 V and 1703 nA as a result of applying vertical tensile lattice strain. More details can be found in article number 2204462 by Yong Soo Cho and co-workers.
