Abstract
Abstract In this thesis, we have utilized synchrotron-radiation photoemission spectroscopy to investigate the adsorption of MgB2 molecules on the Si(001)-2×1 surface. We found that while the MgB2 molecule land on the silicon surface, the MgB2 molecule begins to decompose. It results in the fact that the magnesium and boron atoms are bonded to each of the surface dimer atoms respectively. Furthermore, we discovered the packing method and pressure effect do have an influence on the formation and growth of MgB2 film on the interface.
