Reliable (reported energy within 300 eV of a reference energy)
Comment:
Na-doped (n = 1.7E18 cm-3) As-capped p-GaAs(110)-(1x1) was annealed until Ga was segregated. The chemical shift is referenced to the As metallic state.The Gaussian FWHM represents the intrinsic value, not including the experimental resulution.
