抄録

Lead oxide films which were heated at 880-900 °C, followed by the vaporization at 750-850 °C, and vacuum deposited showed the phenomena of cold emission and negative resistence by the electric-forming. The lead oxide films are detected emission current by application lower voltage, compared with SnO2 films.<BR>The phenomena depended critically on the crack of about 1 (μm) in the films and island structures. The I-V characteristics of the lead oxide films and the relation of their film voltage Vp at which the peak current occurs and energy gaps was qualitatively agreement with Simmons' theory. Therefore, I-V characteristics of planer type device is explicable in a similar as sandwich type device by Simmons' model.
