4 Electrical properties of organic materials

Abstract

Recent research into the electrical properties of low-molecular weight organic solids and polymers is reviewed. Conditions for an effective injection from electrodes into organic solids, and recent views on the photogeneration of charge carriers in photoactive polymers are briefly discussed. The transport of charge carriers in organic materials is reviewed, focusing on disordered (polycrystalline and amorphous) materials. Particular attention is paid to materials potentially applicable as elements of electronic devices: thin film field-effect transistors, and light-emitting and photovoltaic devices.
