Review of Morphology Dependent Charge Carrier Mobility in MEH‐PPV

Abstract Charge carrier mobility in poly(2‐methoxy,5(2′‐ethyl‐hexyloxy)‐p‐phenylene vinylene) (MEH‐PPV) films were measured as a function of temperature and electric field parallel and perpendicular to the substrate for devices prepared from different solvents and under different processing conditions. Bulk structural morphology was characterized by various X‐ray diffraction measurements such as wide angle, small angle and X‐ray reflection. …
