Abstract

Anomalous behavior of trapping and release of charge carriers in poly(methylphenylsilane) films has been discovered by thermally stimulated current spectroscopy. The carrier trapping occurs effectively at room temperature but not at 77 K. Trapped carriers are released at some specific temperatures which do not depend on the heating rate in the measurements. No trapped carrier is released at room temperature. Differential scanning calorimetry indicates that the onset temperatures of the carrier release correspond to the endothermic peaks. Such carrier trapping and release are not observed for polysilanes with saturated hydrocarbon side group but with aromatic side group. Theses results suggest that the observed phenomena are related to the motion of the aromatic substituents.
