Surface Analysis and Hydrogen Permation Measurements for Super-Permeating Membrane Materials

Wong, Chun-Shang; Kolasinski, Robert; Whaley, Josh A.

In this report, we summarize preliminary surface characterization results for Nb surfaces, using low energy ion scattering, direct recoil spectrometry, and Auger electron spectroscopy. While most surface analysis tools cannot detect hydrogen, the low energy ion beam techniques described here are among the few techniques that are directly sensitive to it. For this study, we examined chemisorption using both molecular and atomic hydrogen (using an heated tungsten capillary to dissociate the hydrogen.) To complement these results, we have been performing ex-situ spectroscopic ellipsometry as a means of detecting the surface oxide.
