Abstract

Techniques capable of localized imaging of the structure of hydrogen-bearing crystalline materials at the atomic scale have been conspicuously absent. We show that annular bright field scanning transmission electron microscopy enables the direct imaging of hydrogen atomic columns within a sample of vanadium dihydride, VH2. The suitability of this technique for quantification of the hydrogen content is discussed.
