Electron drift mobilities in liquid long chain hydrocarbons

Major efforts have been made to study the transport properties of charge carriers in polyethylene (PE). However, the results obtained to date are contradictory and the reported mobility values for electrons in PE range over several orders of magnitude.

Most of these data were obtained from time-of-flight measurements in which a break point in the current — time curve was taken as the transit time t
d
. In all these experiments there was insufficient variation of the applied voltage (V) and the sample thickness (d) to verify the relation for the mobility (μ).
