Popis: Charge transport in highly insulating Si backbone polymers has been studied by the Time Of Flight technique. Transit pulse shapes and the field and temperature dependence of the hole drift mobility (for many systems about 10 −4 cm 2 /Vs at 295K and E = 10 5 V/cm) have been characterized for a prototypical example, poly(methylphenylsilylene), PMPS. The effect of dopants, which differ in their relative oxidation potentials, on the drift mobility and the transit pulse shape have also been studied. Comparison of the overall results with other glassy polymeric media suggest that transport proceeds by hopping among chain backbone derived domain like segments.
