dc.description.abstract本文以高解析度X光光電子能譜、反光電子能譜、共振光電子能譜及X光吸收能譜來研究Co-Al合金的電子結構。此Co-Al合金之Co 2p內層能階的不對稱係數比Ni3Al及CoGa為大。這現象表示此Co-Al合金之費米面的能態密度較Ni3Al為大。由X光吸收能譜可知在此Co-Al合金中Co原子的3d電洞數為0.7。zh_tw
dc.description.abstractThe electronic structure of a Co-Al alloy was studied by high-resolution x-ray photoemission spectroscopy, Bremsstrahlung isochromat spectroscopy, resonant photoemission spectroscopy, and x-ray-absorption spectroscopy (XAS) at the L2,3 edges of Co. The asymmetry index of the Co 2p core levels for this Co-Al alloy is larger than that for Ni3Al and for CoGa. This observation implies that the density of states at the Fermi level for this Co-Al alloy should be larger than that for Ni3Al. The number of 3d holes per Co atom is 0.7 as determined from the XAS spectrum.en_US
