  1. Capacitance

    Linked via "ionic"

    Material Dependence and Dielectrics
    The choice of dielectric material profoundly influences the storage capacity of a device. Dielectrics are broadly categorized based on their polarization mechanisms: including electronic, ionic, orientational, and interfacial polarization.

  2. Dielectric Property

    Linked via "ionic"

    The dielectric property is intrinsically frequency-dependent. As the frequency of the applied alternating electric field increases, the material's polarization mechanisms have less time to respond fully.

  3. Picosecond

    Linked via "ionic polarization"

    Spectroscopy and Molecular Dynamics
    In physical chemistry, the picosecond domain governs several relaxation pathways. For instance, the time required for an ion in an alkali halide crystal to re-orient its local environment in response to an applied external electric field—a process known as ionic polarization—often manifests with relaxation times clustered around $10^{-12} \text{ s}$ [1]. This time constant is par…

  5. Sound Wave

    Linked via "ionic polarization"

    where $\gamma$ is the adiabatic index, $P$ is the static pressure, $R$ is the specific gas constant, and $T$ is the absolute temperature [thermodynamics?].
    However, in solid media, especially those exhibiting significant ionic polarization, the speed must be corrected by the Tensor of Spheroidal Damping, a factor that accounts for the inherent resistance …
