Alq3 films have been deposited onto glass substrate using thermal evaporation technique under different experimental conditions. AFM investigations of films revealed that films were homogeneous and crack free with RMS roughness of 4.34 nm. UV-Vis spectroscopy studies of the films show two absorption peaks at a wavelength of about 294nm and 390nm. An intense green colour emission peak is observed at wavelength of about 514nm. Attempts have been made to fabricate ITO/Alq3/Ag heterojunction. The capacitance of junction is shown to be strongly frequency dependent at low frequencies region and tends to attain a constant value at high frequency. The V-I characteristics show that the Alq3 has potential to be used for nonvolatile memory devices.
