Abstract : The results of a series of electrical measurements on thin TiO2 films are described herein. Such films consistently show a negative resistance effect when noble metal electrodes are placed in contact with them. The major portion of this technical report is concerned with ion implantation of single crystal cadmium sulfide. The experimental program studied the effects of group V implants. It was found that bismuth implantations type converted CdS from its natural n-type state. P-n junctions were constructed and room temperature light emission was observed in the forward biased mode. Some of the aspects of low energy ion implantation (25-50 keV) were investigated such as penetration depth and damage. (Author)
