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

Electric Signals on and under the Ground Surface Induced by Seismic Waves

International Journal of Geophysics, 2012
We constructed three observation sites in northeastern Japan (Honjo, Kyowa, and Sennan) with condenser-type large plate electrodes (4 × 4 m2) as sensors supported 4 m above the ground and with pairs of reference electrodes buried vertically at 0.5 m and ...

Demonstrating Vibrational Current Generation With a Self‐Assembled Bioelectret

Advanced Functional Materials, EarlyView.
Vacuum‐deposited films of the plant‐derived molecule, Baicalein, form a self‐assembled bioelectret exhibiting spontaneous orientation polarization and a giant surface potential. The films induce alternating current during the vibration of a movable electrode without charging treatments. Hydrocarbon protection enhances the air stability of the Baicalein

Mimicking Silent Synapse Recruitment: A SiOx/Cu‐Pancake Memristive Device For Analog Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Electroforming‐free TiN/SiOx/Cu/SiOx/TiN memristive devices exploit pancake‐like Cu nanoparticles embedded in a SiOx double layer to create a heterogeneous Schottky‐barrier landscape. Under bias, oxygen‐vacancy redistribution progressively lowers local barriers and recruits initially inactive Cu‐PC pathways into a parallel conduction ensemble, enabling

A fast method to estimate body capacitance to ground at mid frequencies

Journal of Electrical Bioimpedance, 2015
Impedance measurements that involve the human body are affected by the capacitance between the body and earth ground. This paper describes a fast method to estimate that capacitance at 10 kHz, which is valid for impedance analyzers intended to measure ...
