Abstract
In order to grow high quality epitaxial MBE layers, substrates with atomically clean surfaces are required. In this paper we investigated the effectiveness of different wet chemical ex-situ cleaning procedures and an UV/ozone in-situ method on the reduction of interfacial boron and carbon contamination. The carbon desorption was monitored in-situ by XPS. The UV/ozone cleaning reduces the carbon concentration below the detection limit of XPS. Cleaned wafers were coated with silicon and the capped interface was characterized ex-situ by SIMS. By growth interruption the recontamination of an epitaxial layer in ultra high vacuum was investigated. No additional carbon could be detected by SIMS after a growth interruption of 2 hours.
