(1) The accumulation of excessive electric charge in dielectric insulation is extremely rare, but when it does occur, it is often catastrophic.(2) The basic assumption is that electronic dielectric response is everywhere uniform.(3) The dielectric can be air, paper, plastic or anything else that does not conduct electricity and keeps the plates from touching each other.(4) This differs from the usual approach, which embeds the side chain directly within the protein dielectric .(5) An electrically polarizable object will be trapped in a region of a focused electric field, provided there is sufficient dielectric response to overcome thermal energy and the electrophoretic force.(6) The conductance caused by dielectric breakdown of membranes is proportional to the amplitude and duration of the electric field.(7) Under normal circumstances, very few high-energy electrons lodge in the dielectric materials, and most naturally leak away over time.(8) According to another embodiment, the second cover is dielectrically isolated from a current collector.(9) At that size, it expects to make use of new materials and high-k dielectrics .(10) In addition, for systems composed of dielectrically significantly dissimilar regions, ionic energetics is sensitive to the long-range artifacts imposed by periodic boundary conditions.(11) In many photonic structures composed of two or more dielectrics , the absolute value of the refractive index contrast is critical to performance.(12) The dielectrically weighted distance between them had to be > 0.86.(13) But low-k dielectrics improve the insulation between the circuits, thus allowing efficient transistor switching without the need for excessive power, and consequently without the extra heat.(14) It is a dielectrically isolated, high-speed, complementary bipolar IC process that uses a technology called deep trench on bonded wafer, and enables complete dielectric isolation.(15) The magnitude of the first effect depends on the ( dielectrically weighted) relative depth of groups A and B in the membrane.
