摘要：
The transport properties of polyacetylene and polyaniline films have been investigated by electrically detected magnetic resonance (EDMR) at room temperature. In polyacetylene, a spin-dependent interchain tunneling involving a polaron and a soliton is detected. In polyaniline, a similar process is found but involving a polaron-polaron transition. The EDMR signal in polyaniline is found to be dependent on the dc electric field. For low electric fields (F < 1000 V/cm), one resonance line is observed, for higher fields, two resonance lines are observed, having similar g-factors but different linewidths.
