Synchrotron-radiation photoelectron spectroscopy (SRPES) and X-ray photoelectron spectroscopy were used to study the early growth mode of Mn deposited on 6H-SiC(0001) surface and Mn/6H-SiC(0001) interface. The results show that the early growth mode at room temperature can be considered as the 2D layer-by-layer mode. With increasing coverage of Mn
the surface reflected a clear metallic characteristic. During the deposition
Mn was quite stable on the SiC surface
a downward Fermi level movement in band structure measurement was observed and the resultant Schottky Barrier Height (SBH) was estimated at about 1.79 eV. When the deposition height was 2nm
annealing the sample at 250°C could induce Mn to diffuse into the SiC substrate
without any chemical reaction. Further annealing at 500°C there were Mn silicide formation at the interface.
