abstract = {Impact of Non-Stoichiometry and Aliovalent Doping on
Materials Properties of Functional Oxides – from
Ferroelectrics to Lithium-Ion Battery Cathode Materials
Point defects, such as transition-metal dopants or oxygen
vacancies as well as their defect complexes, markedly impact
materials properties and thus determine device performance
and life time. By using dedicated spectroscopic techniques,
the defect structure of oxide ceramics used for energy
conversion and storage is analyzed and the impact of
corresponding defect chemistry to enhance materials
hardening (for piezoelectric compounds), improve the power
density (for lithium-ion batteries) is demonstrated.
Particularly, atomic-scale mechanisms that limit life time
are presented for both types of applications.},
