Dielectric Behavior of α-Ag2WO4 and its Huge Dielectric Loss Tangent [PDF]

Materials Research, 2019
The microwave-assisted hydrothermal method was used to obtain α-Ag2WO4. Rietveld refinement confirmed that α-Ag2WO4 is stable in the orthorhombic phase, without secondary phase.

Dielectric Loss of Boron-Based Dielectrics on Niobium Resonators [PDF]

Journal of Low Temperature Physics, 2019
Advanced solid-state quantum bits (qubits) are likely to require a variety of dielectrics for wiring crossovers, substrates, and Josephson junctions. Microwave superconducting resonators are an excellent tool for measuring the internal dielectric loss of materials. We report the dielectric loss of boron-based dielectric films using a microwave coplanar

Modeling of the evolution of dielectric loss with processing temperature in ferroelectric and dielectric thin oxide films

, 2008
It was experimentally found that the evolution of dielectric loss with processing temperature displays a common trend in ferroelectric and dielectric thin oxide films: firstly an increase and then a decrease in dielectric loss when the processing ...

Universal dielectric loss in amorphous solids from simultaneous bias and microwave field

, 2013
We derive the ac dielectric loss in glasses due to resonant processes created by two-level systems and a swept electric field bias. It is shown that at sufficiently large ac fields and bias sweep rates the nonequilibrium loss tangent created by the two ...
