Conducting polymers comprises a new class of materials achieving electrical conductivities which rival those of the best metals. The parent compounds (conjugated polymers) are quasi-one-dimensional semiconductors. These polymers can be doped by electron acceptors or electron donors. The prototype of these materials is polyacetylene (PA). There are various other conjugated polymers such as polyparaphenylene, polyphenylenevinylene, polypoyrrole or polythiophene. The doped systems, i.e. the conducting polymers, have intersting potential technological applications such as replacement of conventional metals in electronic shielding and antistatic equipment, rechargable batteries, and flexible light emitting diodes.Although these systems have been investigated almost 20 years, the electronic structure of the doped metallic systems is not clear and even the reason for the gap in undoped semiconducting systems is under discussion.

Analysis Calculation

In this paper, the spin transport properties of the coblt dimers parrallel to the transport direction and perpendicular to ransprot direction are investigated by using the first principle analysis. Calculation shows that both the coblt dimers parrallel to the transport direction and perpendicular to ransprot direction give obvious spin polarized density of states and current. It is found that the dimer parrallel to the transport direction have larger spin polarization current.The spin polarized efficiency for the parrallel dimer increase steadily with the increase of the bias voltage. But the the spin polarization for the transverse dimer changes greatly.
