Transmission Electron Microscope Studies of Thin Films of CdSe Vacuum Evaporated from Knudsen-Type Source

Abstract

A Knudsen-type evaporation source was used for the vacuum deposition of thin films of CdSe to study their growth and microstructure on to air-cleaved KCI and mica substrates under different rates of evaporation and substrate temperatures. The conditions for the growth of epitaxial films of this material onto mica have also been established and their photoconducting properties evaluated. CdSe films prepared by this source retain their stoichiometry and compare well with those prepared by other sources of vacuum evaporation.
