Preparation and uses of large area single crystal metal foils

Various preparations and uses of single crystal metals are discussed. We briefly review (i) preparation methods of single crystal metals such as growth from melts, epitaxial deposition in vapors and solutions, and abnormal grain growth in solids and (ii) uses of single crystal metals according to their produced shapes (bulk vs film and foil). We pay special attention to recent advances in the preparation of large area single crystal metal foils and their potential uses. (C) 2019 Author(s).
