Zusammenfassung: | In this manuscript, the authors compare and contrast depth profile data generated on the same commercially available CdTe cell using two analytical techniques, Time of flight secondary ion mass spectroscopy (ToF-SIMS), which is a well-established technique, and radiofrequency pulsed glow discharge (rf-PGD)-ToFMS, which is an emerging technique. The authors demonstrate that pulsed-rf-GD-ToFMS allows for a rapid analysis over a large (4 mm diameter) area of the sample at moderate vacuum conditions, while ToF-SIMS analyzes smaller regions (typically about 200 × 200 μm2) of the sample at ultrahigh vacuum conditions; the authors note that ToF-SIMS enables three dimensional analysis at micron or better lateral resolution. Both techniques show, in general, good agreement; however, some discrepancies are observed and discussed herein. |
