摘要：
Successful deposition of zinc-blende AlN films with thickness up to 1000 Angstrom was performed with plasma source molecular beam epitaxy. The films were epitaxial to the Si(001) substrate. The formation of a thin 3C-SiC layer on the Si(001) surface is one of the important factors for the formation of zinc-blende AlN. Evidence for the presence of 3C-SiC is provided by an Auger electron spectroscopy depth profile and a high-resolution transmission electron microscopy plot profile. Spectroscopic ellipsometry was used to determine the optical constants of zinc-blende AlN in the range from 1.85 to 6.5 eV. The extinction coefficient data indicates that zinc-blende AlN is an indirect semiconductor with a band gap of similar to5.34 eV. (C) 2001 American Institute of Physics.
