Abstract

Raman spectroscopic study of amorphous carbon layers for two different excitation wavelengths at room temperature. The amount of sp3 bondings is estimated to about 10% for both samples, evaluated from the ratio of the D- and G-Raman line intensities. The properties of the bondings in the two samples are discussed. Raman-spektroskopische Untersuchungen von amorphen Kohlenstoffschichten fuer zwei unterschiedliche Anregungswellenlaengen bei Raumtemperatur. Der sp3-Bindungsanteil is zu 10% fuer beide Proben bestimmt worden, ermittelt aus dem Intensitaetsverhaeltnis der D- and G-Raman-Linien. Die Eigenschaften der Bindungen in den beiden untersuchten Proben werden diskutiert.
