Notes:
The temperature dependence of persistent photoconductivity (PPC) has been investigated in high-quality C60 single crystals. We found that the rotational order and disorder phase transition (Tc≈260 K) can significantly change the PPC behavior. At temperatures above Tc, the PPC relaxation rate increases as temperature increases. Quite surprisingly, in the region T〈Tc, the PPC relaxation rate decreases with increasing temperature. Our result clearly indicates that the underlying mechanism of the PPC effect involves the motion of the C60 molecule. © 1996 American Institute of Physics.
