Effects of La-Doping on Strontium Titanate Thin Films
-
Abstract
La-doping effects of strontium titanate (SrTiO3) thin films were studied by x-ray photoelectron spectroscopy. The results indicated that the oxygen adsorption properties of SrTiO3 thin film surface could be significantly affected by La substitution. Besides, a shoulder was observed on the high binding energy side of the main O1s, peak in La-doped thin films.
