1. Capacitance

   Linked via "electronic"

   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 Medium

   Linked via "electronic polarization"

   Ionic Polarization ($\alpha_i$)
   Present in ionic solids and compounds (e.g., alkali halides), this involves the relative displacement of positive and negative ions, leading to a net dipole moment. This mechanism is slower than electronic polarization and contributes significantly to infrared absorption spectra.
   Orientational (or Dipolar) Polarization ($\alpha_d$)

3. Dielectric Property

   Linked via "electronic polarization"

   Ionic Polarization (Atomic Polarization)
   In ionic crystals or ceramics, positive and negative ions are physically displaced relative to each other. This involves the movement of entire charged atoms and is slower than electronic polarization, typically influencing the dielectric response up to infrared frequencies.
   Orientational Polarization (Dipolar Polarization)

4. Dielectric Property

   Linked via "electronic"

   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.

5. Dielectric Property

   Linked via "electronic polarization"

   Low Frequencies: All polarization mechanisms (electronic, ionic, orientational, space-charge) contribute, resulting in the highest $\epsilon_r$.
   Intermediate Frequencies: Orientational polarization begins to lag, causing the permittivity to decrease (dielectric dispersion).
