    • Abstract


      The electrical conductivity of naphthalene doped polystyrene (PS) films (≈ 61.58 𝜇m thick) was studied as a function of dopant concentration and temperature. The formation of charge transfer (CT) complexes and strong concentration dependence of carrier mobility point out that the current carriers are transported through doped polymer system via hopping among sites associated with the dopant molecules. The activation energy, 𝐸a, was calculated from the graph of log𝜎vs 103/𝑇 plot within low and high temperature regions.
