Abstract : Two techniques are described for the deposition of photosensitive layers. One of these is a technique for sensitizing evaporated layers of CdS or CdSe and the other a technique for depositing a resonable reproducible layer of photosensitive material for sintering. Also included are preliminary results of tests to determine a correlation of photoconductivity and gap geometry. Some measurements have been made on the linearity of a resistive strip equal to circumference of a brushless potentiometer. Photoconductivity as a function of sintering time and temperature was studied and showed that there is no apparent correlation. However, photoconductors on Al2O3 are statistically more sensitive than those on glass.
