Unlocking high capacitive energy-density in Sm-doped Pb(Mg_1/3Nb_2/3)O₃-PbTiO₃ thin films via strain and domain engineering.

ABSTRACT: Relaxor ferroelectrics have garnered significant attention in the field of energy storage due to their exceptional properties, such as high recoverable energy density and impressive efficiency. In this work, we explore (001)-oriented and partially strained Sm-doped Pb(Mg_1/3Nb_2/3)O₃-30PbTiO₃ (Sm-PMN-30PT) thin films, prepared by pulsed laser deposition using TbScO₃ substrates and SrRuO₃ electrodes. We employ a comprehensive approach to evaluate the structural, compositional, and energy storage properties of Sm-PMN-30PT thin films. Our study demonstrates an ultra-high energy density of 116 J cm^-3 and an efficiency of 73%, along with excellent thermal stability and fatigue-free energy storage properties in Sm-PMN-30P
