摘要

The early stages of oxidation of aluminum nitride have been studied by transmission electron microscopy and electron diffraction. It has been found that the oxide layer grows by the Stranki-Krastonow mechanism, where an initial uniform layer is followed by island formation. The onset of oxidation occurs at 800 deg. C and the initial oxide phase that fOrms is γ-Al_2O_3, one of the transition aluminas. The orien1ation relationship between the oxide layer and the underlying nitride is (440)_γ||(l l20)+ain and [ll2]_γ ||[01l0]_ain
