초록

We have studied conduction mechanism that is interpreted in terms of space charge limited current (SCLC) region and tunneling region. The OLEDs are based on the molecular compounds, N,N'-diphenyl-N,N'-bis(3-methylphenyl)-1,1'-biphenyl-4,4'-diamine (TPD) as a hole transport, tris (8-hydroxyquinolinoline) aluminum(III) $(Alq_3)$ as an electron injection and transport and emitting layer. We manufactured reference structure that has in $ITO/TPD/Alq_3/Al$. Buffer layer effects were compared to reference structure. And we have analyzed out electrical conduction mechanism in $ITO/Alq_3/Al$ device with various temperature.
