Herein, we report a cryogenic-temperature study on the evolution of ferroelectric properties epitaxial Hf0.5Zr0.5O2 thin films silicon. Wake-up, endurance, and fatigue these are found to be intricately correlated, strongly hysteretic, dependent available thermal energy. Field-dependent measurements reveal decrease in polarization with temperature, which has been determined not an intrinsic change material property, rather demonstration increase coercive bias material. Our findings suggest...
Heat treatment of cubic YbZrF7, after quenching from 1000 °C, leads to a material displaying precisely zero thermal expansion at ∼300 K and negative lower temperatures. The is associated with minimum in the lattice constant K. X-ray total scattering measurements are consistent previously proposed model which incorporation interstitial fluoride into ReO3-related structure both edge corner sharing coordination polyhedra. temperature dependence experimental pair correlation functions suggests...
Herein, we examine the influence of controllable polarization reversal and built-in electric fields on pyroelectric electrocaloric effects in a BaTiO3 thin film using modified indirect method. We find that magnitude sample's change with temperature is sensitive to degree reversal. The response small at low fractions switched grows larger by several factors as are reversed. This reversal-sensitive behavior result an internal field, which has effect destabilizing producing diminished effect....
Nanostructure transition metal oxides (MO-type M = Fe, Co, Ni, Cu, . ) with rock-salt structure are promising anode materials to be used in lithium ion batteries, when compared conventional graphite anodes due their superior Li- ions storage capability. NiO nanostructures were successfully grown onto stainless steel 304 substrates using a low pressure chemical vapor deposition process at 600°C and characterize morphology-dependent electrochemical behavior room temperature. Structure...
The objective of this work is to develop a durable MEMS sensor for in situ monitoring advanced reactor piping. Existing sensors structural health (SHM) nuclear environments have limited temperature ranges and service lifetimes, owing material constraints. Micromachined transducers using aluminum nitride (AlN) as sensing element, silicon carbide (SiC) substrate, the potential address challenge. In work, piezoelectric Ultrasonic Transducers (pMUT) capable delivering passive (acoustic emission)...
Nanostructure transition metal oxides (MO-type M = Fe, Co, Ni, Cu, . ) with rock-salt structure are promising anode materials for lithium ion batteries. These types of can store two to three times the capacity graphite (372 mAh g-1) which is state-of-the-art technology. Here we focus on growth Nickel oxide (NiO) prepared by chemical vapor deposition (CVD) directly current collectors and understanding origin excess capacity. The synthesis NiO nanoplates CVD ideal studying electrochemical...
