| Summary: | The influence of n-type doping on the electronic structure of Cd2SnO4 has been studied by electron-energy-loss spectroscopy (EELS) and UV photoemission spectroscopy (UPS). In substitution on Cd sites or Sb substitution in Sn sites leads to the appearance of well-defined plasmon loss peaks in EELS, with a maximum plasmon energy of just below 0.6 eV in Sb-doped material. A weak conduction-band feature is observed in UPS, the width of which is of the order expected from a simple free-electron model. |
