Reflection electron energy loss spectroscopy and x-ray photoemission spectroscopy results obtained from laser-ablated amorphous CN[sub x] thin films have been analyzed in order to quantitatively deduce the change of the threefold/fourfold carbon coordination ratio induced by the nitrogenation. It has been found that nitrogenation induces an increase of the threefold-coordinated carbon atoms with respect to the fourfold-coordinated ones, evidencing the graphitization of the material. All the bond concentrations of the threefold and fourfold coordinations have been evaluated. © 2001 American Institute of Physics.

    The band alignment and thermal stability for HfO2 films on SiC with and without nitridation have been studied by using photoemission spectroscopy. The valence- and conduction-band offsets at HfO2/4H-SiC interfaces were measured to be 1.02 and 1.53 eV, respectively. The atomic source nitridation...
