STUDY OF BOMBARDMENT-INDUCED-CONDUCTIVITY MATERIALS

Abstract

Research was conducted to obtain the theoretical and experimental data concerning enhanced bombardment-induced-conductivity which would make possible the development of a direct-view storage tube with high resolution, selective erasure, and the simultaneous display of stored and nonstored information. Further experimental confirmation of a correlation between increasing crystal size and higher values of the conduction ratio was needed. It was established previously that thermal processing of the ZnS increases the crystal size and that 300 C thermally processed films exhibited about twice the value of the conduction ratio of non-thermally processed films. Measurements were made on films thermally processed at 450 and 600 C. X-ray diffraction patterns indicated that these films exhibited progressively larger size crystals than 300 C processed layers. Both the 450 and 600 C thermally processed layers exhibited conduction ratio values lower than those of the 300 C thermally processed layers, but higher than those of the non-thermally processed layers. This new evidence suggests that factors other than crystal size play a significant role in the bombardment induced-conductivity effect.
