We report on the interface between graphene and $4\mathrm{H}\text{\ensuremath{-}}\mathrm{Si}\mathrm{C}(0001)$ as investigated by scanning tunneling microscopy (STM) and low energy electron… Expand
Stable surface reconstructions on 6H–SiC(0001̄)
- J. Bernhardt, M. Nerding, U. Starke, Klaus Heinz
- Materials Science
- 30 July 1999
Abstract We used scanning tunneling microscopy (STM), low energy electron diffraction (LEED) and Auger electron spectroscopy (AES) to identify and investigate stable surface reconstructions on… Expand
Comparison of the relative bioavailability of different coenzyme Q10 formulations with a novel solubilizate (Solu™ Q10)
- C. Schulz, U. Obermueller-Jevic, O. Hasselwander, J. Bernhardt, H. Biesalski
