空間電荷極限傳導是測量半導體材料載子遷移率的方法之一. 在此論文中, 我們測量共軛有機高分子,
poly(2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vunylene) 或稱 MEH-PPV. 我們同步執行電流與電容對偏壓關係的測量, 藉由此法, 我們可以驗證樣品是否達到空間電荷極限. 我們觀察到了特殊的遷移率對電場與溫度的關係, 而結果的討論是利用了能量不準度的跳躍模型.

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.
