| Summary: | 碩士 === 國立臺灣大學 === 物理學研究所 === 88 === Space charge limited transport is one of the ways of measuring
carrier mobility in semiconducting materials. In this work,
measurements have been performed on conjugated organic polymer,
poly(2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vunylene) or
MEH-PPV. A simultaneous current and capacitance versus applied
voltage measurement was carry out to validate the space charge
limited conduction. An anomalous electric field dependence was
observed and discussed within the framework of energy disorder
hopping model.
