Rare‐earth‐incorporated low‐dimensional chalcogenides: Dry‐method syntheses and applications

Chalcogenide thin films incorporating rare‐earth (RE) elements with applications in optics, electronics, and magnetics have received considerable attention. Aiming at growing pure chalcogenides, dry‐method syntheses have been developed. In this review, we summarize the progress thus far on low‐dimensional RE‐based chalcogenides (RECs), covering fabrication methods, structures, and applications. This review also provides the summary and perspectives of the challenges of fabrication and opportunities on the application of RECs in the future.
