| Research Abstract |
In this study, we challenged to grow epitaxial thin films of simplest hydride LiH to establish techniques essential to high quality thin film growth of hydrides, which are class of materials attracting attention as electrolytes of the future technology, thin film lithium ion batteries. The LiH epitaxial thin films were successfully obtained by hydrogenating liquid-Li on a MgO(100) substrate at temperature higher than the melting point of Li. In addition, simulation study revealed growth mechanism of the LiH epitaxial thin film that gives direction for epitaxial thin film growth of various hydrides.
