Abstract

The influence of antimony pentafluoride vapour on the electrical and optical properties of C₆₀ films is investigated. Exposure at room temperature is seen to have no influence, whereas a visible colour change is observed at elevated temperatures. The optical absorption spectrum is dominated by the features of the untreated sample above the band edge, but, in the region of the edge, a significant loss in oscillator strength is observed. The d.c. conductivity of the treated sample is three orders of magnitude higher than that of the C₆₀ film and is seen to increase by a further eight orders on heating to 400 K. The temperature dependence is, however, nonmetallic and is nonreversible. This initial heat cycle is interpreted as an annealing process resulting in further indiffusion of the p-dopant.
