Inside Cover: Resolidified Chalcogen Precursors for High‐Quality 2D Semiconductor Growth (Angew. Chem. Int. Ed. 29/2023)

Resolidified chalcogen precursors provide stable chalcogen supply in chemical vapor deposition growth of 2D semiconductors and improve their structure and luminescence uniformity, as illustrated in the cover picture and detailed by Bilu Liu et al. in their Communication (e202301501). Low defect density and sharp photoluminescence of monolayer semiconductors are achieved, promoting their applications in optoelectronics.
