Abstract
The optical transition in a beta-FeSi2 film has been characterized by phetoreflectance. The direct transition has been determined to be at 0 .874 eV. Moreover, a direct transition at 0.860 eV has also been obser ved and might be related to the impurity band. The reflectivity of the beta-FeSi2 films was investigated, and a transition near 1.2 eV was o bserved. Finally, a comparison of spectroscopic ellipsometric measurem ents on different samples is given.
