Thin film samples have been prepared by evaporating a commercial fullerene C-60 powder from a tungsten crucible, at a pressure of 10(-5) Pa onto quartz or Coming glass substrates. Samples were equipped with coplanar Cr-Au electrodes evaporated onto the surface of the film. Dark conductivity measurements in the range 300 K - 600 K reveal the existence of hysteresis phenomena. Thermal annealing influences photoconductivity and changes the power coefficient in the power-law illumination-intensity dependence of photoconductivity.

Abstract
Thin film samples have been prepared by evaporating a commercial fullerene C-60 powder from a tungsten crucible, at a pressure of 10(-5) Pa onto quartz or Coming glass substrates. Samples were equipped with coplanar Cr-Au electrodes evaporated onto the surface of the film. Dark conductivity measurements in the range 300 K - 600 K reveal the existence of hysteresis phenomena. Thermal annealing influences photoconductivity and changes the power coefficient in the power-law illumination-intensity dependence of photoconductivity.File in questo prodotto:
