A statistical picture of dielectric breakdown in solids is presented and discussed in this paper. The morphology selection mechanism is described by the stochastic model or model. The approach is formulated in terms of two functions () and (), which play the role of a free energy and that ...
The dielectric constant of the membranes is determined to maintain the Debye screening length equal to 10−7 m. This value, which is larger than the actual λ in Nafion™ membranes, is utilized to model high surface electrodes that significantly increase the capacity of the electric double...
The maximum Vg that can be applied without dielectric breakdown is ∼2,000 V, which allowed us to reach maximum pressures around 30 kPa; the uncertainty in P is below 5% for all voltages. The deflection of the graphene membranes under applied pressure was determined via interferometric ...
Dielectric elastomers (DEs) respond to applied electric voltage with a surprisingly large deformation, showing a promising capability to generate actuation in mimicking natural muscles. A theoretical foundation of the mechanics of DEs is of crucial importance in designing DE-based structures and devices....
Such breakdown of ergodicity is a type of partitioning process [41] and results in no change in the enthalpy or volume of a system, i.e., it is not a first-order thermodynamic phase transition. However, the loss of ergodicity does entail a loss of configurational entropy since the ...
, and acoustic field, and combining with two kinds of damage mechanisms. The multiphysics model considers the influence of electrode shape, electrode angle, and electrode spacing on the HEPD rock breaking. From the obtained multi-physics model, it is found that the formation of the breakdown...
According to Hays and Kendall’s law [19], it is assumed that the applied load “P” is partially affected by small resultant pressure “W,” which is a function of material under investigation. “W” is thus the minimum applied load required to cause a plastic deformation. Hays and ...

However, in the case in which voltages per unit thickness are higher with a decrease in a thickness of the dielectric layer, dielectric breakdown may readily occur even when low voltage is applied. In general, when voltage is applied to a multilayer ceramic capacitor, an electric field is conc...
The invention relates to a high-dielectric constant metal/ceramic/polymer composite material and a method for producing an embedded capacitor. As ceramic particles having a relative
