Charge Carriers Generation in Thin Polymer Films by Weak External Influences
A.N. Lachinov, R.B. Salikhov, A.A. Bunakov and A.R. Tameev

The paper considers the features of the charge transport near to the threshold of the transition of the thin poly(diphenylenephthalide) films both from insulator into the high-conductivity state, induced by a small uniaxial pressure. Two independent methods were used to measure a drift mobility of charge carriers in the polymer films. The electric field and temperature dependences of hole and electron mobility were explored. It was also shown that the effect of uniaxial pressure leads to increase both hole and electron mobility. It is concluded that charge carrier transfer in thin polymer films is probably explained by the hopping mechanism through traps.
