Epitaxial thin film growth of ion conductive hydrides for development of solid electrolytes

在这项研究中，我们挑战生长最简单的氢化物LiH的外延薄膜，以建立对高质量的LiH薄膜生长至关重要的技术，LiH是一类作为未来技术薄膜锂离子电池的电解质而引起关注的材料。在MgO（100）衬底上，用高于Li熔点的温度氢化Li，成功地获得了LiH外延薄膜。此外，模拟研究揭示了LiH外延薄膜的生长机理，为不同晶型的外延薄膜生长提供了指导。

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.
