Unlocking high capacitive energy-density in Sm-doped Pb(MgNb)O-PbTiO thin films strain and domain engineering.

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(MgNb)O-30PbTiO (Sm-PMN-30PT) thin films, prepared by pulsed laser deposition using TbScO substrates and SrRuO electrodes. We employ a comprehensive approach to evaluate the structural, compositional, and energy storage properties of Sm-PMN-30PT thin films.
