Abstract
We have investigated the valence bands of the tiophosphates FEPS3 and NiPS3 with the resonant-photoemission technique. Some structures of the energy distribution curves show rapid intensity changes when the photon energy is scanned across the Fe or Ni 3 p absorption thresholds. Instead, other structures show smooth excitation spectra. We have related the former to the transition metal ion 3 d states (direct photoemission and satellites) and the latter to the (P2S6)4- states. These results support also a strongly ionic picture of these compounds. © 1984 Società Italiana di Fisica.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
