dc.description.abstract
The thermodynamics of hydrogen absorption in Pd-capped Mgfilms are strongly dependent on the magnesium thickness. In the present work, we suppress such dependency by inserting a thin Ti layer between Mg and Pd. By means of optical measurements, we show that the surface energy contribution to the destabilization of MgH2 is negligible. The inserted Ti layer prevents Mg-Pd alloy formation at the Mg/Pd interface, leading to quasifree Mgfilms and enhancing the kinetics of hydrogen desorption. Our observations are important for the development of thin film devices.
