摘要：
Transport and generation processes of ionic impurity carriers in amorphous polymethylphenylsilane (PMPS) have been investigated by a voltage reversal method. The ionic carriers in PMPS are likely to be sodium ions because PMPS was prepared by condensation of an organosilicon dichloride monomer with sodium dispersion. The drift mobility and its activation energy of the ionic carriers are determined to be 1.2x10(-9) cm(2)V(-1)s(-1) at 323 K and 0.64 eV, respectively. The generation of the ionic carriers is found to be dependent on applied electric field and temperature. It is shown that the electric field dependence of the generation process can be explained by the Poole-Frenkel mechanism. Copyright (C) 1996 Elsevier Science Ltd
