Interface injection-limited carrier-transport properties of Alq3

Effect of doping on optical and transport properties of charge carriers in Alq3

“…The injection barrier between Alq 3 and Al cathode can be considerably reduced by inserting an intermediate layer such as LiF, NaF, NaCl, etc. [8]. It is believed that an intermediate state participating in the injection process, so that the injection does not occur in a single hop.…”

“…Although transport is dominated in this case by the effects of disorder, electric field screening by the metal contact also reduces the LUMO and the HOMO splitting energy at the interface. The carrier injection properties of Al cathode can be described by the charge hopping mechanism [8]. The problem of carrier injection at the cathode has been treated in terms of the orbital energies of the electrode and the electron transporting material.…”

The nature of the electrical conduction and light emitting efficiency in organic semiconductors layers: The case of [m-MTDATA] – [NPB] – Alq3 OLED

“…Especially, the use in light emitting diodes has been shown to have a potential field of application [1,2] and some simple devices have been fabricated and tested [3][4][5]. The attractive properties include the very high optical absorption coefficients, relative facility of doping, low refractive index and low density of intrinsic defects as compared to inorganic materials.…”
