Quantum Saturation of the Electro‐Optic Effect

Advanced Materials, EarlyView.
At low temperatures, quantum fluctuations saturate the ferroelectric soft mode, suppressing thermal sensitivity in functional properties. By tuning the phase boundaries of ferroelectric materials to 0 K, large temperature insensitive electro‐optic effects are realized, establishing a pathway toward high‐efficiency optical modulation for quantum ...

Perfluorinated Organosilicons Enabling Low‐Loss Ferroelectric Polymer Composites for Efficient Energy Storage and Electroluminescence

Advanced Science
Ferroelectric polymers for energy storage and conversions suffer from high energy losses. Despite great efforts in polymer composites with organic or inorganic fillers, limited successes are achieved with an often compromised dielectric constant (K ...

Ferroionic‐Assisted, Charge‐Driven Polymorphic Phase Engineering for Multilevel Memristive Devices

Advanced Materials, EarlyView.
A CuInP2S6/Mo0.92W0.08Te2 heterostructure enables a gradual semiconductor‐to‐semimetal phase transition through Cu+ ion migration and charge accumulation. The spatially engineered 2H/1T′ mixed phases produce continuously tunable conductance states in a two‐terminal geometry, while suppressing depolarizing fields and stabilizing the metastable 1T′ phase.

UV laser induced ferroelectric domain inversion in lithium niobate single crystals [PDF]

, 2010
UV radiation in the spectral region beyond ~ 320 nm is strongly absorbed by lithium niobate single crystals. The strong absorption and the consequent localized heating of the crystal triggers physical processes which can affect the state of the material ...

Charge‐Trapping Multilayer Electrets for Partial Discharge Mitigated AlN Substrates

Advanced Materials Interfaces, EarlyView.
Multilayer electret films deposited on AlN substrates trap injected charge and generate an opposing electric field at the triple point. Finite‐element simulation shows the retained charge reduces the local field by about one third. Under steep high‐voltage pulses, the charged stacks raise the partial discharge inception voltage and lower the discharge ...
