Dopant Concentration Controls Quasi-Static Electrostrictive Strain Response of Ceria Ceramics.

ABSTRACT: Electromechanically active ceramic materials, piezoelectrics and electrostrictors, provide the backbone of a variety of consumer technologies. Gd- and Sm-doped ceria are ion conducting ceramics, finding application in fuel cells, oxygen sensors, and, potentially, as memristor materials. While optimal design of ceria-based devices requires a thorough understanding of their mechanical and electromechanical properties, reports of systematic study of the effect of dopant concentration on the electromechanical behavior of ceria-based ceramics are lacking. Here we report the longitudinal electrostriction strain coefficient (M₃₃) of dense RE_xCe_1-xO_2-x/2 (x ≤ 0.25) ceramic pellets, where RE = Gd or Sm, measured under am
