Abstract
Results from measurements of the hydrogen uptake in Mo/V single-crystal superlattices with modulation wavelengths (\ensuremath{\Lambda}) from 0.3 to 17.7 nm are presented. These studies were performed by hydrogen profiling, using the $^{1}\mathrm{H}$${(}^{15}$N,\ensuremath{\alpha}\ensuremath{\gamma}${)}^{12}$C reaction, and x-ray diffraction. The average hydrogen to metal ratio was found to decrease for decreasing \ensuremath{\Lambda}. For \ensuremath{\Lambda}\ensuremath{\ge}13 nm, large structural changes are observed, while for \ensuremath{\Lambda}\ensuremath{\le}5.5 nm no structural changes were observed upon hydrogenation. A model describing the modulated-wavelength dependence of the hydrogen uptake is proposed.
