Abstract. Charge carrier transport properties of radiation — polymerized amorphous and crystalline poly(N-vinylcarbazole) layers have been investigated. Poole-Frenkel conductivity in the former and space charge limited current flow in the latter case have been observed. Field and temperature dependencies of the charge carrier mobility and the respective activation energies have been determined.
