AN IONIC THERMOCURRENT SPECTROMETER.
Abstract
An investigation of the relaxation of electric dipoles produced by doping polycrystal CaF2 with NaF was carried out by means of Ionic Thermo Currents (I.T.C.). The I.T.C. measurements were conducted in the temperature range from 77K to room temperature. These measurements show one main peak and three lesser peaks. The main peak is believed due to the (Na(+)-VF(-)) dipole and shows an activation energy for reorientation of .55 eV and a To of 1.5 x 10 to the -15th power. As yet little is known about the two peaks occurring at the lowest temperatures; however, the third peak fits the published data for the (O(=)-VF) dipole. Further investigation is proceeding on this problem. (Author)
