Abstract
A new techiniquc for the preparation of AIN thin films by ultrahigh vacuum electron beam evaporation of Al followed by nitridation is reported and by using this method c-axis oriented A1N thin films have been successfully grown on Si(111) substrates. X-ray diffraction, Fourier transform infrared spectroscopy, x-ray photoelection spectroscopy and cross-sectional transmission electron microscope were employed to characterize A1N films. Temperature of nitridation was found to play an important role in the formation of A1N film. By post-nitridation of as-deposited film at 1000°C for 1h in N2, the crystallinc A1N film with (002) orientation has been obtained.
