Reliable (reported energy within 300 eV of a reference energy)
Comment:
0.2ML and 3.0 ML Y/Si(111)-(7x7). Principal peak whose binding energy is constant with yttrium coverage. But from coverage between 2.3 and 3.0 ML the Si2p presents a shoulder located at 1.4 eV lower binding energy. Si(111)-c(7x7) was n-type P-doped with
