Poor electrical conductivity and large volume expansion during repeated charge and discharge is what has characterized many battery electrode materials in current use. This has led to 2D materials, specifically multi-layered 2D systems, being considered as alternatives. Among these 2D multi-layered systems are the graphene-based van der Waals heterostructures with transition metal di-chalcogenides (TMDCs) as one of the layers.

- The study investigates the effects of lanthanide doping (about 2% concentration) on the properties of MoS monolayers using advanced computational methods (DFT+U), focusing on elements like Ce, Eu, Gd, Lu, and Tm.
- It finds that Eu, Gd, and Tm can significantly increase the magnetization of MoS while showing half-metallic behavior in certain doped systems, indicating a potential for magnetic semiconductors.
- The doping also improves the optical characteristics and photocatalytic properties of MoS, resulting in a shift of optical absorption to lower energies and notable changes in electron energy loss and dielectric properties.
