Cu 2p core levels spectra measured by X-ray photoemission spectroscopy of selected as-grown Nd2âxCexCuO4+δ samples are presented and discussed. The presence of a satellite peak in the 2p core level of Nd2âxCexCuO4+δ single crystal by hard X-ray photoemission is confirmed in all non-superconducting samples, films and single crystals investigated in this work. The comparison of the spectral features of the different samples suggests that the presence and the intensity of this satellite peak is not related to the electric transport properties, but to the texture characteristics.

Abstract
Cu 2p core levels spectra measured by X-ray photoemission spectroscopy of selected as-grown Nd2âxCexCuO4+δ samples are presented and discussed. The presence of a satellite peak in the 2p core level of Nd2âxCexCuO4+δ single crystal by hard X-ray photoemission is confirmed in all non-superconducting samples, films and single crystals investigated in this work. The comparison of the spectral features of the different samples suggests that the presence and the intensity of this satellite peak is not related to the electric transport properties, but to the texture characteristics.File in questo prodotto:
