Synthesis Methods of Two-dimensional Rare-earth Materials

Abstract In recent years two-dimensional rare-earth materials have rapidly become a frontier and hot spot in sci entific research due to their unique properties that combine those of two-dimensional materials and rare-earth materi als.To achieve the application of two-dimensional rare-earth materials in the fields of optics electronics and mag netism their synthesis is of crucial importance.The methods for synthesizing two-dimensional rare-earth materials have been summarized.Among them chemical vapor deposition (CVD) is one of the commonly used methods and salt-assisted CVD can be used to synthesize binary (such as GdO CeO EuO etc. ) and ternary (such as EuO Cl LaOCl ErOS etc. ) two-dimensional rare-earth compounds mechanical exfoliation is often used to synthesize two-dimensional rare-earth oxyhalides and tellurides coating methods include molecular beam epitaxy thermal de position and others which can be used to synthesize GdSi EuGe 2 SmSe etc. Finally the prospect of large-scale synthesis of two-dimensional rare-earth materials have been proposed.
