Ferroelectric and incipient ferroelectric properties of a novel Sr9-xPbxCe2Ti12O36 (x=0-9) ceramic system

We revealed that Sr9Ce2Ti12036 is an incipient ferroelectrics with the R-3c trigonal structure. The subsequent substitution of Sr by Pb enhances permittivity and induces a ferroelectric phase transition to monoclinic Cc pha...

Dynamics of the phase transitions in Bi-layered ferroelectrics with Aurivillius structure: Dielectric response in the terahertz spectral range

We have investigated the dielectric response in the terahertz (THz) spectral range of a series of Bi-layered ferroelectrics with Aurivillius structure involving ferroelectric compounds (Bi4Ti3O12, SrBi2Ta2O9, SrBi2Nb2O9), a...

Mapping sliding ferroelectricity in bulk (PbS)1.11VS2 crystals

The recent discovery of sliding ferroelectricity opens up the field of 2D ferroelectricity. However, the limitation to switching the polarization due to the topological protection of the domain walls limits the potential of these het...
