| Summary: | This report examines the electrical properties of ice in the frequency range of 0-10 (7) Hz, attempting to be suitable both as a simple and clear textbook for students and non-specialists and as a comprehensive review of recent developments and discoveries in the field. Corresponding to this double goal, the report consists of two parts. The first one is written in textbook style and contains most general theoretical and experimental results essential for understanding of unique electrical properties of ice. The theoretical interpretation of ice conductivity and ice dielectric permittivity is based on ice being a protonic semiconductor. Jaccard's elegant model is used to mathematically describe the electrical properties, and is expanded on cases of ice samples having finite size, boundaries and interfaces, and an inhomogeneous electric field. The statistics of charge carriers in pure and doped ice is discussed in detail, as are experimental techniques for measurements of conductivity and dielectric permittivity. The first part contains a comprehensive review of experimental results on ice conductivity, ice dielectric permittivity, mobility and electric charges of protonic charge carriers and activation energies of their generation and motion. |
