摘要:

XPS core level and valence band spectra are presented for a chemically etched epitaxial thin film of superconducting HgBa2CaCu2O6+δ(Tc= 123 K) on a SrTiO3(100) substrate. These data exhibit lower levels of high binding energy contaminant signals in the O 1sand alkaline earth core level regions compared to studies in the literature, and a clear Fermi edge in the valence band region, evidence of a high quality surface.

摘要:

XPS core level and valence band spectra are presented for chemically etched epitaxial thin films of superconducting TlBa2CaCu2O7−δ, one of which is as-grown overdoped (superconducting transition temperature [Tc] = 74.5 K) and two which are annealed (Tc= 86.5 K and 87.5 K). The core levels measured from the annealed films are shifted to higher binding energies relative to those from the as-grown overdoped film, consistent with a doping-induced change in the chemical potential.

摘要:

XPS core level and valence band spectra are presented for chemically etched epitaxial thin films of superconducting Tl2Ba2CuO6+δon SrTiO3(100) substrates which are as-grown overdoped (superconducting transition temperature [Tc]=11 K) and annealed (Tc=63 K). The core levels measured from the annealed film are shifted to higher binding energies relative to those from the as-grown overdoped film, consistent with a doping-induced change in the chemical potential.

摘要:

We present here the changes in the valence band and the C 1score peak and its shake-up satellite of a C60film upon photopolymerization using x-ray photoelectron spectroscopy. It was found that the intensity of the C 1sshake-up satellite of the phototransformed C60film decreased with increasing irradiation time of 500 W mercury lamp (0 to 200 h). On the other hand, the valence band spectra of the C60film was almost unchanged even after 200 h of irradiation, compared with that of pristine C60film.

摘要:

X-ray photoelectron spectroscopy was used to analyze poly(cis-isoprene). The polymer was centrifugally spin cast on a silicon wafer. We find that thecisspectrum can be described by five Voigt profiles. The parameters of the lines with standard deviations are found by least-square fitting.
