Abstract

The nature of chalcogenides as electrets is virtually an unexplored arena. Electrets now exist in a variety of forms such as the electroelectret, thermal electret, photoelectret, radioelectret and magnetelectrets. An investigation of selenium as a dielectric is employed using the method necessary for the preparation of thermal electrets. The effect of the various parameters such as charging time, charging temperature and sample dimensions are investigated and observed. From these observations a conclusion can be made to the type of preferred orientation taking place in the material; be it dipole orientation, ion transfer or carrier displacement.
