Abstract

We present high-resolution XPS spectra of elemental vanadium, niobium and tantalum sputter-cleaned by Ar⁺ ions. The energy scales are shown without applying any corrections, and the position of the Fermi level was verified to be at zero binding energy within better than 0.1 eV, as determined from the Fermi edge measurement.
