Notizen:
We have observed a persistent photoconductivity effect (PPC) in C70 films well above room temperature. The effect, which consists of a metastable increase in dark conductivity caused by brief exposure to light, exhibits characteristics very similar to the PPC previously observed in C60 films. These characteristics include a magnitude of the effect independent of the light exposure temperature, the existence of a PPC even at 520 K, and the inability of subgap illumination to create or quench PPC. A common origin for the PPC in C70 and C60 seems plausible, and may be related to the distortions the fullerene molecules experience when charged.
