Revealing the Giant Electromechanical Effects in Yttria-Stabilized Zirconia Single Crystal. [PDF]

Adv Sci (Weinh)
Giant electromechanical responses are uncovered in yttria‐stabilized zirconia single crystal (SC‐YSZ), exhibiting pronounced orientation dependence. The giant electrostriction and piezoelectricity are directly correlated with the long‐range transport kinetics of oxygen vacancies.
