Abstract

The electrochemical quartz crystal microbalance (QCMB) was applied to the study of amorphous La-Ni thin film electrodes. Amorphous LaNi5 thin films were deposited on both AT and BT cut quartz crystal substrates by physical vapor deposition in ultrahigh vacuum. The electrochemical QCMB measurements determine the mass loading of hydrogen atoms (H) as well as the stress in the film upon H insertion. These experiments also allow in situ monitoring of hydrogen absorption-desorption and oxidation-reduction reactions in metal hydride thin film electrodes.
