High-resolution angle-resolved photoemission study of the Ag band structure alongΛ

Resolving the Pu electronic structure enigma: Past lessons and future directions

“…For many materials, this has proven to be a strong test of the electronic structure [12]. In fact, recent studies of U valence band structure have been successfully carried out [13].…”

Does band mapping find its limits in the soft X-ray range?

“…In order to investigate the possibility of performing accurate band mapping experiments in the soft X-ray energy range, Silver (Ag) has been chosen as a well known metal whose electronic band structure has been extensively studied both from a theoretical [15][16][17][18][19][20][21] and an experimental point of view [22][23][24][25][26][27][28][29][30]. Measurements along one high symmetry direction have been recorded for different values of both the incoming photon energy and the temperature.…”

Observation of an underlying relativistic effect in the valence bands of Pt

“…Viewing the Pt 5d states as shallow cores is not completely unreasonable: classical band-mapping studies of Pt [26,27], Au [27] and Ag [28] all point toward a picture of somewhat localized d states where the effective crystal field and spin-orbit splitting separate the components of the d manifold at the Brillioun zone center and hybridization with the sp bands provide much of the observed dispersion. If there were a significant remnant of localization in the Pt 5d states, then the strong selection rules against bulk emission, predicted by group theory for three-dimensional periodic systems with strong delocalization, might fail and the underlying atomic selection rules could come into play.…”
