摘要：

We have measured the temperature dependence of the coefficients b and gamma in the expression sigma(p) = bF(gamma), where F is the light intensity and sigma(p) is the photoconductivity of C-60 films. Interpretation of the results in terms of an exponential density of gap states, assumed to be generated by disorder in the electronic potential, indicates that this disorder decreases with decreasing temperature below 260 K.
