Oxygen vacancy (VO), the most common type of defect in metal oxides, could alter intrinsic
properties which are usually determined by crystal structures. Oxygen-deficient metal oxides …

Energy storage devices (ESD) are getting significant attention regarding their ability to
reduce fossil fuel usage. Batteries and electrochemical supercapacitors are two well‐known …

Cation segregation on perovskite oxide surfaces affects vastly the oxygen reduction activity
and stability of solid oxide fuel cell (SOFC) cathodes. A unified theory that explains the …

While FIB sample preparation for transmission electron microscopy is a well established
technique, few examples exist of samples of sufficient quality for atomic resolution imaging …

Revealing whether dislocations accelerate oxygen ion transport is important for providing
abilities in tuning the ionic conductivity of ceramic materials. In this study, we report how …

Ferroelectric interfacial devices consist of materials systems whose interfacial electronic
properties (such as a 2D electron gas or an interfacial magnetic spin configuration) are …

Electro-mechanical interactions between charged point defects and domain walls play a key
role in the functional properties of bulk and thin-film ferroelectrics. While for perovskites the …

Although elastic strains, particularly inhomogeneous strains, are able to tune, enhance or
create novel properties of some nanoscale functional materials, potential devices dominated …

Studies on dislocations in prototypic binary and ternary oxides (here TiO2 and SrTiO3) using
modern TEM and scanning probe microscopy (SPM) techniques, combined with classical …

Dislocations have been considered to be an efficient source for scattering midfrequency
phonons, contributing to the enhancement of thermoelectric performance. The structure of …
