Hafnium oxide (HfO2) is one of the mature high‐k dielectrics that has been standing strong
in the memory arena over the last two decades. Its dielectric properties have been …

Black phosphorus (BP) is a rapidly up and coming star in two‐dimensional (2D) materials.
The unique characteristic of BP is its in‐plane anisotropy. This characteristic of BP ignites a …

Piezoelectricity allows precise and robust conversion between electricity and mechanical
force, and arises from the broken inversion symmetry in the atomic structure,,. Reducing the …

Due to the nature of domains, ferroics, including ferromagnetic, ferroelectric, and ferroelastic
materials, exhibit hysteresis phenomena with respect to external driving fields (magnetic …

The origin of the unexpected ferroelectricity in doped HfO2 thin films is now considered to be
the formation of a non-centrosymmetric Pca21 orthorhombic phase. Due to the …

A progressive reduction of tetragonal distortion, heat of transition, Curie temperature, and
relative dielectric constant has been observed on dense BaTiO 3 ceramics with grain size …

There has been a resurgence of complex oxides of late owing to their ferroelectric and
ferromagnetic properties. Although these properties had been recognized decades ago, the …

▪ Abstract This paper reviews the literature on size effects in ferroelectric materials, with an
emphasis on thin film perovskite ferroelectrics. The roles of boundary conditions, defect …

In this review, the main concept of ferroelectricity of perovskite oxides and related materials
at nanometer scale and existing difficulties in the synthesis of those nanocrystals are …

We report on the investigation of ferroelectricity in thin tetragonal single-crystalline
perovskite films of Pb (Zr 0.2 Ti 0.8) O 3 grown by off-axis rf magnetron sputtering. The local …
