We report the electron and hole drift mobilities and the recombination lifetime in thin polycrystallineC60films. The data are obtained from photocurrent measurements involving an optical interference grating moving at variable velocity across the sample surface. Considerable degradation of the transport parameters is observed as the samples are exposed to air. The initial values for the electron and hole drift mobilities are1.3±0.2 cm2/V sand(2±1)×10−4 cm2/V s,respectively, and for the recombination lifetime(1.7±0.2)×10−6s. ©1997 American Institute of Physics.
