Field Dependent Currents in n-Tridecane

Conduction currents have been measured in neat n-Tridecane under stepped voltage with a 50 ns rise time in a point-plane geometry with a 3.5 μm point radius. Currents are observed under both polarities with similar onset threshold. Larger currents are recorded under negative polarity. The shape and polarity dependence of the charge recordings indicate that the charge is generated in the bulk, but charge injection from the needle electrode cannot be ruled out.
