Thin films of polyacrylonitrile obtained by vacuum deposition were made semiconductive by the heat-treatment in N_2. Electrical condtuctivity and Hall mobility have been measured for the films heat-treated at various temperatures. Conductivity increases and the activation energy for conduction decreases with increasing heat-treatment temperature. Hall mobility is small (10^<-1>〜10^<-4>cm^2/V.s) and has nearly the same activation energy as that of conductivity. Hall measurements indicate the evaporated films to be n-type while the thermoelectric power exhibits p-type. These results suggest that the conduction should be understood in terms of the hopping transport of charge carriers in the localized states which are formed in the forbidden band by random networks of conjugate double bond systems of carbon to carbon and carbon to nitrogen.
