摘要

Electrical measurements were made on insulating and semiconducting Gd3+:CdF2(Ce3+) samples. The gadolinium concentration was held at .02 mole % while the cerium concentrations were .006, .02 and .06 mole %. Samples were heated at 520C in a Cd vapor for 30 minutes and quenched to room temperature. Various electrode metals were studied, including Ag, In, Hg-In alloy and Au. The techniques of applying these electrodes included vacuum deposition, thermal soldering and ultrasonic soldering. Complex dielectric constants were measured over the frequency range of 50 Hz to 20 MHz. The large real dielectric constants found were attributed to a depletion layer formed within the sample. A voltage dependent capacitance was observed. Bulk resistivities were obtained using a pulse technique. (Author)
