SURFACE PHOTOCONDUCTIVITY OF ANODICALLY GROWN ZNO LAYERS

Surface photoconductivity of thin, anodically grown ZnO layers, separa ted from the maternal zinc substrate and glued onto a slice of organic glass, has been investigated. The effect of spectral sensitization wi th erythrosin on the photoconductivity of anodic ZnO layers has alo be en studied. The width of the forbidden energy gap in investigated mate rial, estimated from the experimentally determined spectral distributi on of the photosensitivity equals 3.3. eV.
