Quantitative Analysis of Residual Hydrogen on Platinum Surface by Atom Probe

The paper reports results of a systematic investigation of electric field effects on residual H signals in atom probe analysis. Three species, H+, H2+, and H3+, can be detected on a Pt surface without gas introduction into the ultra-high vacuum chamber. The H+ ions are more likely to be detected at...

description	The paper reports results of a systematic investigation of electric field effects on residual H signals in atom probe analysis. Three species, H+, H2+, and H3+, can be detected on a Pt surface without gas introduction into the ultra-high vacuum chamber. The H+ ions are more likely to be detected at a higher electric field. On the other hand, the H2+ and H3+ ions appear at the lower electric field. A comparison of residual H and a D2 gas confirmed that residual H is in the H2 gas form. H2 can be dissociated to H on the Pt surface. Consequently, H, H2, and H3 coexist on the Pt surface and desorb at an appropriate electric field.
