Abstract
The technique of secondary ion mass spectrometry (SIMS) has been employed to detect Bi+3 ions and associated oxides Bi3O+x (x ≈ 1 to 4) from a Bi foil. Using a 3 keV Ar+ ion primary beam of 5 × 10-7 A/cm2, mass resolution to nearly 700 with the requisite sensitivity has been achieved. The Bi surface was also monitored by X-ray photoelectron spectroscopy (XPS or ESCA). The presence of a weak O 1s peak at 532.7 eV and a strong SIMS Bi+3 peak is interpreted to mean that the oxygen is weakly incorporated into the Bi lattice without disrupting metalmetal bonds.
