Enhancing discharged energy density and suppressing dielectric loss of poly(vinylidene fluoride-ter-trifluoroethylene-ter-chlorofluoroethylene) by a sandwiched structure

IET Nanodielectrics, 2018
Polymer dielectrics with high energy density and low dielectric loss are highly desired due to the rapid development of electric devices. Among known polymers, poly(vinylidene fluoride-ter-trifluoroethylene-ter-chlorofluoroethylene) P(VDF-TrFE-CFE) is ...

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene

Advanced Functional Materials, EarlyView.
Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...

SYNTHESIS AND CHARACTERISATION OF DIELECTRIC COMPOSITES PRODUCED FROM GLYCINE AND ALKALINE NIOBATE-BASED CERAMICS

Mağallaẗ Al-kūfaẗ Al-handasiyyaẗ
Glycine exhibits a little piezoelectric response when poled, while lead-free alkaline niobate-based ceramics show much higher responses. This research investigates the synthesis of a dielectric composite from a combination of glycine and (K0.45Na0.51Li0 ...

Hydrogen-terminated diamond field-effect transistor with a bilayer dielectric of HfSiON/Al2O3

AIP Advances, 2020
The fabrication of a single-crystal hydrogen-terminated diamond metal-oxide-semiconductor field-effect transistor (MOSFET) with HfSiON/Al2O3 bilayer dielectric has been carried out. HfSiON and Al2O3 layers were deposited by sputtering-deposition (SD) and

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights
