Zusammenfassung

We studied the infrared transmission of different epitaxial graphene samples and could verify the Dirac like behavior of the charge carriers in the vicinity of the Dirac points K and K'. Individual Landau level transitions could be identified and evaluated. In addition, we investigated new properties, which occur in an absorption line splitting, leading to different Fermi velocities. One, with a value of 1.03x10^6 m/s, which is in agreement with former studies of epitaxial graphene, and another one with about 1.08x10^6 m/s. After peeling the samples, we could identify graphene layers on the epitaxial as well as on the exfoliated part by Raman scattering. Studying the transmission of the remaining epitaxial parts, we observed a disappearance of the absorption peak of the higher Fermi velocity.
