Abstract : A system for fabricating electroluminescent CdS diodes from platelet material and assembly equipment and techniques for mounting the diodes were developed. The necessary electronic equipment for measuring electrical properties of the diodes was completed. The diodes were prepared by depositing a thin film of Cu and diffusing the Cu into the crystal to form the blocking contact and then depositing In for the ohmic contact. Results indicated that reasonably efficient hole injection was achieved based upon the low threshold voltage of 1.7 volts necessary for the onset of electroluminescence. Current-voltage and differential capacitance measurements confirmed that the diodes were p-i-n structures. (Author)
