We have performed electric-field and temperature-dependent electron injection studies in an aluminum/tris(8-hydroxy-quinolinolato)aluminum/magnesium single-layer organic light-emitting diode. Analysis of the observed injection currents in terms of the classic Fowler-Nordheim (FN) tunneling or Richardson-Schottky (RS) thermionic emission proved to be inadequate. Whereas, the FN-type behavior at high-electric fields must be considered accidental, the injection currents qualitatively resemble those of the RS concept. However, quantitative differences are observed concerning the RS coefficient, the prefactor current, and the temperature dependence. On the other hand, the experimental data are in excellent agreement with a recently presented Monte Carlo simulation [U. Wolf et al., Phys. Rev. B 59, 7507 (1999)] of carrier injection from a metal to an organic dielectric with random hopping sites. © 1999 The American Physical Society.
