Doped Polymers

Charge-dipole interaction effects in molecularly doped polymers are discussed. The charge-dipole Coulomb interaction makes exponentially distributed traps. Calculating the mobility with their traps leads to mobility behavior like Gill's equation. The cancellation of a dipole corresponds to coincidence events of small-polaron hopping.

Small-polaron hopping involved in charge transport in Fe-doped congruent lithium niobate is investigated as a function of temperature and composition by means of light-induced transient absorption spectroscopy. The relaxation dynamics of the light-induced polaron population is characterized by individual activation energies within different temperature ranges. A numerical investigation carried out by Monte Carlo simulations reveals that these findings may be understood in terms of the varying abundance of the different types of hops that the polarons may perform among regular or defective lattice sites. The role of the temperature and of the sample composition on the distribution of the different hop types is thus explored for a wide range of parameters, allowing one to preview the charge transport properties for a given set of experimental conditions.
