The objective of this work was a phenomenological study of materials which exhibit electron bombardment-induced conductivity BIC as well as sustained electron bombardment-induced conductivity SEBIC for application to novel display devices. These devices are 1 a direct-view storage tube with high resolution, selective erasure, and the ability to display stored and nonstored information simultaneously, and 2 a high resolution storage tube containing no meshes. The operation of the direct-view storage tube is reviewed and criteria are established for advantageous use of a BIC dielectric in direct-view storage tubes. The meshless storage tube operation is analyzed, and the required SEBIC material characteristics are established. The theory of bombardment-induced conductivity is defined and related to the materials requirements. Data are presented on the BIC and SEBIC effects in thin films 12 micron of zinc sulfide and cadmium sulfide. Author
