Abstract : A summary of the work on CdS is presented, and it is concluded that resistivity of the evaporated films does not depend on the controlled evaporation parameters. It is observed that gold substrates are destroyed by the evaporation of CdS onto a 300 C substrate whereas platinum substrates are not. The evaporation of CdS has been dropped in favor of CdSe which appears to be a more reproducible system. The range of 0.95 eV hot electrons in gold films has been photoelectrically determined to be 330 = 30 angstrom units. This value is obtained with gold films on chemically prepared silicon as well as samples cleaved in an evaporating gold stream. A discussion of the range measurements is presented, and this value of range is compared to that measured by other investigators. (Author)
