摘要：

The composition and chemical structures of lanthanum oxide films were determined by combining angle-resolved photoelectron spectroscopy and high resolution Rutherford backscattering studies. Conduction and valence band discontinuity at La2O3/Si(1 0 0) interface was also determined by measuring the O 1s photoelectron energy loss and valence band spectra. (C) 2004 Elsevier B.V.
