Atom Probe Tomography as an Emerging Tool for Understanding Defect‑Driven Mechanisms in HfO2‑Based Ferroelectrics

Advanced Functional Materials, EarlyView.
This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...

Noise‐Limited Bit Precision in Ferroelectric Synaptic Transistors for High‐Resolution Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...

Dielectric properties of individual cryoprotective agents and cocktails VS55, M22, DP6 at subzero temperatures for cryopreservation

Scientific Reports
A range of electromagnetic (EM) rewarming approaches are being studied with the potential to enable organ cryopreservation. EM heating of materials, including cryoprotective agents (CPAs), is mainly governed by dielectric properties (dielectric constant ...

Dielectric Losses of Doped Colored Crystals

The Journal of Chemical Physics, 1957
The dielectric losses of KBr single crystals doped with BaBr2 at different concentrations, both uncolored and additively colored, have been measured. A maximum in the dielectric loss versus frequency curve in the additively colored crystal was observed. This relaxation maximum was found to be due to the presence of Z2 centers.

Losses of the parallel-plate dielectric resonator

IET Microwaves, Antennas & Propagation, 2006
The various loss aspects of the parallel-plate microwave dielectric resonator for the TE 01delta mode is studied from a modified field model. The main merit of this field model is that it provides very simple electromagnetic field expressions of this field mode. Various methods of calculation of losses are discussed.
