介电质(Dielectric material) 先分析一下绝缘体,外部电场会造成绝缘体内部载流子的位移,以产生诱导偶极子。某些绝缘体中存在永久偶极子,他们会在外部电场的作用下对齐,有永久偶极子的材料成为极化材料,反之则为非极化材料。 而在金属中(metal),自由移动的电子立即消除材料中的电场变化(屏蔽固定的正离子),外部电场被表...
The dielectric polarisation occurs when a dipole moment is formed in an insulating material because of some externally electric field applied to it.This can be observed when current interacts with an insulating (dielectric) material for a long time, the later will respond with a shift in charge ...
Dielectric polarization refers to the alignment of charges in a dielectric material under the influence of an external electric field, leading to the creation of induced electric dipole moments and polarization charges on the material's surface. AI generated definition based on: Physics Reports, 2015...
The theorem holds if the permittivity tensor ϵ in Equation (5) is asymmetric instead of symmetric, as the off-diagonal elements contribute to non-reciprocal phenomena, such as Faraday rotation33. In Equation (5), ϵxy is the off-diagonal element of the dielectric tensor, whereas diagonal ...
is 7% at the operating wavelength of 633 nm. The efficiency could be improved by applying more precise fabrication procedures, using low-loss dielectric materials (such as TiO2) or reducing the coverage angles of the holographic image. More details about the efficiency calculation and measurement...

Dielectric film Energy storage Polarization Strength Loss Energy-storage dielectric capacitors have emerged as one of the key technologies for high-power systems such as green energy generation, hybrid/electrical vehicles, pulsed power devices, etc. [1] The high-power feature of dielectric capacitors ...
Understanding the mechanisms underlying a stable polarization at the surface of ferroelectric thin films is of particular importance both from a fundamental point of view and to achieve control of the surface polarization itself. In this study, we demons
In principle, the slow down in growth rate for large PTO polarization is not reliant on the ferroelectric nature of BTO, a dielectric material should similarly experience an energy penalty when polarization is imposed on it. However, for the frequently studied case of SrTiO3grown on PTO on SrTi...
