Halide perovskites have gained tremendous attention in the past decade owing to their
excellent properties in optoelectronics. Recently, a fascinating property, ferroelectricity, has …

Ferroelectrics are inseparable from symmetry breaking. Accompanying the paraelectric-to-
ferroelectric phase transition, the paraelectric phase adopting one of the 32 crystallographic …

Originating from a broken spatial inversion symmetry, ferroelectricity is a functionality of
materials with an electric dipole that can be switched by external electric fields …

Ferroelectricity results from one of the most representative phase transitions in solids, and is
widely used for technical applications. However, observations of ferroelectricity in organic …

A summary of recent work is presented describing the synthesis and characterization of
noncentrosymmetric or homochiral metal-organic coordination compounds (MOCCs) or …

Ferroelectrics based on proton tautomerism are promising in low-field and above-room-
temperature operations. Here seven organic ferroelectric crystals are examined to search for …

The field of ferroelectricity has greatly expanded and changed in recent times. In addition to
classical organic and inorganic ferroelectrics, new fields and materials, unknown or inactive …

Water confined on the scale of 20 Å, is known to have different transport and thermodynamic
properties from that of bulk water, and the proton momentum distribution has recently been …

Hydrothermal treatment of a solution of water or deuterium oxide containing N-4-
cyanobenzylcinchonidine bromide (CBCBr), NaN3, and Zn (NO3) 2· 6H2O at 105° C gave …

The second harmonic generation (SHG) responses of the paraelectric and ferroelectric
phases of KH2PO4 (KDP) were calculated by first-principles density functional theory (DFT) …
