Ferroelectrics in Photocatalysis
Chemistry – A European Journal, 2022AbstractThe rapid development of industrialization and population has brought water, air‐pollution and energy crises. Solar‐driven catalysis is expected to relieve these issues. However, limited by poor light harvesting, serious charge recombination of semiconductors, and high surface reaction barriers, the low efficiency of solar conversion is far ...

Role of Point Defects in the Formation of Relaxor Ferroelectrics
Social Science Research Network, 2021Relaxor ferroelectrics are engineered by doping a large amount of point defects into normal ferroelectrics. The point defects create nanoscale compositional heterogeneity, which in turn lead to local Curie temperature ( T C ) variation and random local ...

Ferroelectricity and Ferroelectric Phase Transition
2013Ultrathin crystalline films offer the possibility of exploring phase transitions in the crossover region between two and three dimensions. Second-order ferromagnetic phase transitions have been observed in monolayer magnetic films.

Effect of ferroelectric parameters on ferroelectric diodes
Journal of Applied Physics, 2012We investigate the effect of various ferroelectric parameters, such as the doping density, the permittivity, and the thickness, on ferroelectric diodes based on the proposed self-consistent numerical model. Our calculations clarify the dependence of the band diagrams, the charge density distributions, and the I–V curves on these important ferroelectric

Science, 1989
In the past year it has become possible to fabricate ferroelectric thin-film memories onto standard silicon integrated circuits that combine very high speed (30-nanosecond read/erase/rewrite operation), 5-volt standard silicon logic levels, very high density (2 by 2 micrometer cell size), complete nonvolatility (no standby power required), and extreme ...

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 solids have until recently been limited to well-known polymer ferroelectrics and only a few low-molecular-mass compounds.

Long‐range ordering of dipoles is a key microscopic signature of ferroelectrics. These ordered dipoles form ferroelectric domains, which can be reoriented by electric fields.
