Zusammenfassung
Spectroscopic ellipsometry has been used to determine the dielectric functions of ultrathin Ge/Si superlattices with varying strain states and periodicity at room temperature. The E1-like transitions could be resolved with the multiple-angle-of-incidence technique and in a thick, Ge-rich sample; they split up into various contributions and start to absorb the light at lower energies than ...
