Abstract : Experiments on the diffusion of Se in ZnSe were made. This and earlier work indicate that in all the II-IV compounds the chalcogenide component diffuses by a mechanism other than simple vacancy diffusion. This result is of fundamental importance to an understanding of the defect structure of these materials. The electrical properties of the different components of ZnSe sub X Te sub (1-x) light emitting diodes at 80K have been investigated. The current-voltage characteristic of the junction region agrees with classical junction theory. Under self-illumination, the currents carried by the n- and p-type bulk regions were ohmic. The major current-limiting factor is the electrical contact to the p-type side of the junction. A mask changer and evaporation rate monitor are being assembled in order to improve the reproducibility of the GaAs switching diodes. Resistivity measurements of evaporated GaAs films yielded values in the 100,000 ohm-cm range at 300K. No Hall mobility has yet been detected. (Author)
