Infrared spectroscopic study of chromium film growth on single crystal diamond — •Robert Lovrincic and Annemarie Pucci — Kirchhoff-Institut für Physik der Universität Heidelberg

Detectors made of single crystal diamond are currently being developed for several tasks in particle physics experiments. One important step towards satisfying detector performance is the metallization. As chromium is a carbide forming metal and therefore shows good adhesion to the diamond surface, we studied the system Cr/C(100) by means of infrared spectroscopy under ultra high vacuum conditions. By analysing the obtained spectra with a Drude type dielectric function, we are able to distinguish between different phases in the film growth and to derive information about the electrical conductivity of the metal layer.
