| Abstract: | The emitting process of organic thin film electroluminescent devices with single heterojunction is analyzed and calculated by taking advantage of Gauss's law based on Fowler Nordheim equation. The calculated results demonstrate that, in electroluminescent devices with single heterojunction, the redistribution of electric field leads to the enhancement of minority injection and reduction of majority injection. The enhancement of the minority results in the improvement of luminescent efficiency with the reduction of majority injection resulting in the falling of current level. |
