Abstract

The composition and chemical structures of lanthanum oxide/Si(100) system were determined by applying the maximum entropy concept to the angle-resolved Si 1 s and La 3d photoelectron spectra. The results obtained are as follows: The compositional depth profile of lanthanum oxide/Si(100) structure was not affected by the annealing in nitrogen gas under atmospheric pressure at 300°C, while that was affected by the annealing at temperature above 400°C. The analyses of O 1s and Si 1s spectra indicated that the lanthanum silicate was produced by the deposition of lanthanum oxide on Si(100) and the amount of lanthanum silicate increases by the annealing at temperature above 400°C.
