摘要


本論文著重於有機發光二極體(Organic Electroluminesence Display, OLED)中載子傳輸的特性研究。 根據有機材料中載子以跳躍(Hopping)方式進行導電的假設下,利用降低環境溫度、增加電場強度、縮放元件尺寸和改變有機層厚度的實驗方式,觀察溫度與載子遷移率、電場與載子遷移率以及電壓電流的依存性。為了從暫態電激發光現象(Transient electroluminesence)實驗中求得載子遷移率,我們採用簡化過的方程式來近似整體電激發光延遲時間(Electroluminesence delay time),根據此算式推算出Alq3中的電子遷移率(u)。

In this master thesis, we focus on carrier transport characteristic of organic light emitting Diode at low temperature. According to the assumption that the carriers in organic material transport by jumping(hopping), we try decreasing ambient temperature, increasing strength of electric field, scaling device size and changing the thickness of the organic layer for observing the dependence on temperature and carrier mobility, electric field and carrier transport and I-V curve. In order to obtained the value of carrier mobility from transient electroluminesence experiment, we've simplified formula to approximate electroluminesence delay time, and calculated Alq3 carrier mobility based on this formula.
