Dielectric Absorption in Lithium Fluoride

Dielectric Absorption in Lithium Fluoride

The dielectric loss in single crystals of lithium fluoride has been examined between temperatures of 0°C and 130°C. At the lower temperatures the dielectric loss, as a function of frequency, passes through a definite maximum and is quite distinct from the background loss due to dc conductivity. From...

Zusammenfassung:The dielectric loss in single crystals of lithium fluoride has been examined between temperatures of 0°C and 130°C. At the lower temperatures the dielectric loss, as a function of frequency, passes through a definite maximum and is quite distinct from the background loss due to dc conductivity. From the experimental results, the frequency factor (7×1012 sec—1) and energy barrier (0.65 ev) are derived. After darkening with x-rays the absorption disappears and reappears again after bleaching.
