Abstract
ZnS/Au/ZnS (ZAZ) films which are nano-multilayer and transparent conductive films, were fabricated on quartz substrates at different substrate temperatures via pulsed laser deposition, and the influences of substrate temperature on the structural and optoelectrical characteristics of ZAZ films were researched. X-ray diffraction (XRD) diagrams show that the crystallinity and the quality of the films are improved at higher substrate temperatures, and scanning electron microscope (SEM) show that the film’s surface becomes dense and rough. The substrate temperature also seriously affects the optoelectronic characteristics of ZAZ films. When the substrate temperature is increased, the figure of merit for the ZAZ films decreases. When substrate temperature is 20 ℃, the ZAZ film has the largest figure of merit value (3.34 × 10–3 Ω−1), with an average transmission of 81% in the visible region and a carrier concentration of 1.91 × 1021 cm−3. Transparent, conducting ZAZ films have great potential applications in high-performance optoelectronic devices.
