Apparatus and improved procedures for the vacuum co-evaporation of thick CdS films 5 to 15 microns are described. A correlation between the thickness of CdS film piezoresonators, their resonant frequency and the electrode areas, required for the 50 ohm impedance matching, was worked out. First film resonances as distinguished from substrate resonances with Q of about 15 were observed in gold-CdS-gold piezoelectric structures, deposited on thin and thick glass substrates.
