Origin of dielectric relaxor behavior in PVDF-based copolymer and terpolymer films

AIP Advances, 2018
Relaxor ferroelectrics exhibit frequency-dispersion of their dielectric permittivity peak as a function of temperature, the origin of which has been widely debated. Microscopic understanding of such behavior for polymeric ferroelectrics has presented new

Geometric isotope effect of deuteration in a hydrogen-bonded host–guest crystal

Nature Communications, 2018
Deuterating a hydrogen bond can change the bond’s geometry, a phenomenon known as the geometric isotope effect (GIE). Here, the authors find that a hydrogen-bonded host–guest crystal, imidazolium hydrogen terephthalate, exhibits significant GIE on its ...

Some current problems in perovskite nano-ferroelectrics and multiferroics : kinetically-limited systems of finite lateral size [PDF]

, 2015
We describe some unsolved problems of current interest; these involve quantum critical points in ferroelectrics and problems which are not amenable to the usual density functional theory, nor to classical Landau free energy approaches (they are ...
