Long viewed as a topic in classical physics, ferroelectricity can be described by a quantum
mechanical ab initio theory. Thin-film nanoscale device structures integrated onto Si chips …

Advances in complex oxide heteroepitaxy have highlighted the enormous potential of
utilizing strain engineering via lattice mismatch to control ferroelectricity in thin-film …

Electrocaloric effects have been experimentally studied in ferroelectrics and incipient
ferroelectrics, but not incipient ferroelectrics driven ferroelectric using strain. Here we use …

Using epitaxy and the misfit strain imposed by an underlying substrate, it is possible to
elastically strain oxide thin films to percent levels—far beyond where they would crack in …

Fluctuating orders in solids are generally considered high-temperature precursors of broken
symmetry phases. However, in some cases, these fluctuations persist to zero temperature …

Ferroelectrics have a spontaneous electrical polarization that is arranged into domains and
can be reversed by an externally applied field. This high versatility makes them useful in …

Predictions and measurements of the effect of biaxial strain on the properties of epitaxial
ferroelectric thin films and superlattices are reviewed. Results for single-layer ferroelectric …

Vertically aligned nanocomposite thin films with ordered two phases, grown epitaxially on
substrates, have attracted tremendous interest in the past decade. These unique …

Polar topological structures such as skyrmions and merons have become an emerging
research field due to their rich functionalities and promising applications in information …
