中文摘要	the electron mobilities of tris(8-hydroxy-quinolinato) aluminum (alq(3)) thin films at various thicknesses (70-280 nm) have been determined by using admittance spectroscopy measurements. our results show that the electric field dependence of electron mobilities exhibits different behaviors at different thicknesses of alq(3) films. clearly, when the thickness of alq(3) film is less than 150 nm, the electron mobilities slightly decrease with increasing the electric field. for the thickness of alq(3) film more than 150 nm, however, the mobilities increase as the electric field increases. the phenomena are well discussed by energetic disorder. using temperature dependent i-v characteristics, we further calculated the density of traps.
