Although only a few 2D materials have been predicted to possess ferroelectricity, 2D
ferroelectrics are expected to play a dominant role in the upcoming nano era as important …

Ever since the beginning of this century, many kinds of materials have been reported to
demonstrate colossal permittivity (CP) or a colossal dielectric constant exceeding 103 …

Magnetism and ferroelectricity are essential to many forms of current technology, and the
quest for multiferroic materials, where these two phenomena are intimately coupled, is of …

Direct manipulation of the atomic lattice using intense long-wavelength laser pulses has
become a viable approach to create new states of matter in complex materials …

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 …

Capacitors are a mainstay of electronic integrated circuits and devices, where they perform
essential functions such as storing electrical charge, and blocking direct current while …

The competition between collective quantum phases in materials with strongly correlated
electrons depends sensitively on the dimensionality of the electron system, which is difficult …

For over 70 years, ferroelectric materials have been one of the central research topics for
condensed matter physics and material science, an interest driven both by fundamental …

Softening of the transverse optical (TO) phonon, which could trigger ferroelectric phase
transition, can usually be achieved by enhancing the long-range Coulomb interaction over …

We demonstrated that ultraviolet Raman spectroscopy is an effective technique to measure
the transition temperature (T c) in ferroelectric ultrathin films and superlattices. We showed …
