Popis: |
Electroconductivity of sandwich structures with films based on photoconductive poly-N-epoxypropylcarbazole and nonphotoconductive polyvinylethylal doped by organic dyes with coordinated boron and metal atoms is studied. Generally, the electroconductivity is due to (1) a drift of ions, (2) a thermal and field generation of holes from uncontrolled extrinsic centers and electrons and holes from dopant molecules, and (3) a thermal and field injection of electrons and holes from electric contacts. The electroconductivity of structures with thin polymer films that have a high dye concentration is defined by the transport of charge carriers in the dye aggregates. |
