온도 변화에 따른 유기 전기 발광 소자의 전압-전류 특성

Current-Voltage Characteristics of Organic Light-Emitting Diodes with a Variation of Temperature

초록

- Temperature-dependent current-voltage characteristics of organic light-emitting diodes(OLEDs) were studied in a device structure of ITO/TPD/Alq3/Al to understand conduction mechanism. The current-voltage characteristics were measured in the temperature range of 8K ∼ 300K. We analyzed an electrical conduction mechanism of the OLEDs using space-charge-limited current(SCLC) and Fowler-Nordheim tunneling. In the temperature range above 150K, the conduction mechanism could be explained by space charge limited current from the inversely proportional temperature dependence of exponentm`
