Paper Abstract

In this paper we discuss the space charge field formation process in poly(N-vinylcarbazole)-based photorefractive polymers and more specifically its relation to charge transport. In the steady state, the experimental results are found to be in qualitative agreement with the predictions of the standard model. A large saturation field, that corresponds to a trap density of the order of 5 multiplied by 1016 cm-3 is estimated. In the transient regime however, the space charge field departs from its expected behavior: this is shown to arise due to the influence of disorder on the charge transport process.
