| Abstract(in English) | We have investigated electron injection barrier height at aluminum tris (8-hydroxy-quinoline) (Alq_3)/cathode interfaces by internal photoemission (IPE) measurement. A three layered device consisting of ITO/TiO_2/IL/Alq_3/cathode structure was used to fabricate the "electron-only device". The measured barrier heights were 0.86, 1.05, 1.3 and 1.55eV for MgAg, Al, Ag and Au electrodes. Barrier height showed linear relationship with work-function and electro-negativity of cathode materials. The slope parameter of 0.6 with electro-negativity was attributed to the interfacial charge transfer through the mid gap electronic states at the cathode/Alq_3 interface. |
