Characterization of electronic states using a polarized light and a display analyzer

The applicability of the recently-developed method (called ODAD: orbital de termination from angular distribution) to analyze and assign atomic orbital s, such as pz or dx2-y2, constituting a valence band from observed two-dime nsional photoelectron angular distributions(PEAD) is discussed systematical ly. The two-dimensional PEAD pattern obtained by using a linearly polarized light are characteristic For the initial atomic orbital, and we can deduce the component ratio of atomic orbitals constituting the valence band by fi tting the observed PEAD to the calculated patterns. When the observed regio n is limited by the band structure effect, it is shown that we can deduce t he component ratio of atomic orbitals by rotating the sample even though th e atomic orbitals have the same magnetic quantum number m.
