Abstract

The electrical conduction mechanism of ITO / Terbium tris - (1 - phenyl - 3 - methyl - 4 - (tertiarybutyryl) - pyrazol - 5 - one) triphenylphosphine oxide [$(tb-PMP)_3Tb-(Ph_3PO)$]/Mg/Al devices has been investigated. The calculation of electric field in single layer organic layer between cathode and anode shows the uniform distribution for the electron injection barrier of over 1.4 eV. The measured current-voltage curve shows well matching with the calculated curve based on the tunneling injection of electron under the uniform distribution of electric field.
