The physicochemical parameters of nanomaterials, includ-ing the size, shape, core
structure, and surface ligands, govern the properties as well as the utilities of nanomaterials …

Infrared (IR) spectroscopy has evolved into a powerful analytical technique to probe
molecular and lattice vibrations, low-energy electronic excitations and correlations, and …

In ferroelectric-based photovoltaic materials, spontaneous polarization is expected to couple
with the electronic and optical properties of the materials, and such materials have drawn …

In ABO3-type perovskite oxides with Pnma symmetry, rotation (QR+, a 0 a 0 c+) and tilt (QT,
a–a–c0) of BO6 octahedra are the two primary order parameters. These order parameters …

The primary order parameter of hybrid improper ferroelectricity (HIF) is not spontaneous
polarisation but nonpolar modes such as oxygen octahedral rotations (OORs), antipolar, or …

Recent studies carried out with atomic force microscopy or high-resolution transmission
electron microscopy reveal that ferroic domain walls can exhibit different physical properties …

We employ synchrotron-based near-field infrared spectroscopy to reveal the vibrational
properties of bulk, few-sheet, and single-sheet members of the M PS 3 (M= Mn, Fe, Ni) family …

As a new group of van der Waals (vdWs) ferroic materials, transition metal dioxydihalides
MO2X2 (M: Mo, W; X: halogen) with a perovskite‐like structure are theoretically predicted to …

We combined synchrotron-based near field infrared spectroscopy and atomic force
microscopy to image the properties of ferroelastic domain walls in Sr3Sn2O7. Although …

Hybrid improper ferroelectrics (HIFs) have been studied intensively over the past few years
to gain an understanding of their temperature-induced phase transitions and ferroelectric …
