| Abstract(in English) | Electric-field-induced optical second-harmonic generation (EFISHG) technique was employed to investigate the transient electric-field distribution in organic electroluminescent diode, i.e., IZO/NPB/Alq/Al structure device. Electric field relaxation was found to occur where the device was biased to exhibit enhanced electroluminescence. On account of Maxwell-Wagner effect, charge accumulation process at the NPB/Alq3 interface was analyzed. It was shown that holes accumulated at the NPB/Alq interface. The charge accumulation time was longer than the expected hole transit time across NPB layer. |
