Impedance of carrier injection at the metal-organic interface mediated by surface states in electron-only tris(8-hydroxyquinoline) aluminium (Alq<sub>3</sub>) thin layers
Garcia-Belmonte, Germà; Bisquert, Juan; Bueno, Paulo R.; Graeff, C. F. O. Elsevier (2008)Capacitance spectra of thin (<200 nm) Alq<sub>3</sub> electron-only devices have been measured as a function of bias voltage. Capacitance spectra exhibit a flat response at high frequencies (>10<sup>3</sup> Hz) and ... -
Kinetics of interface state-limited hole injection in α-naphthylphenylbiphenyl diamine (α-NPD) thin layers
Garcia-Belmonte, Germà; Bisquert, Juan; Bueno, Paulo R.; Graeff, C. F. O.; Castro, F. A. Elsevier (2009)Injection-limited operation is identified in thin-film, α-NPD-based diodes. A detailed model for the impedance of the injection process is provided which considers the kinetics of filling/releasing of interface states as ...
