Abstract :
The physico-chemical state of silicon atoms present in the HfO2/SiO2/Si system is studied by X-ray emission spectroscopy induced by electrons. From the analysis of the Si 3p occupied valence states the very thin oxide interfacial layer is characterized. From the simulation of the spectra and the calculation of the emissive thicknesses, the silicon oxide thickness is determined to be one or two monolayers, depending on the sample. The presence of point defects at the interface is also suggested.
