Optical Modification of TMD Heterostructures.

ABSTRACT: Optical modification is a fast, cost-effective, and scalable approach to tailoring the physical properties of two-dimensional (2D) materials for various applications. However, most previous efforts have focused on modifying individual 2D materials, which fails to utilize the method to its fullest potential. In this paper, heterostructures composed of hBN-capped molybdenum ditelluride (MoTe₂) and molybdenum disulfide (MoS₂) are optically modified with a continuous wave laser. The process simultaneously thins MoS₂ and induces clustering of tellurium atoms from the ablated MoTe₂. These structural changes result in significant enhancements of the physical properties, including a 43-fold increase in MoS₂ photoluminescence and the transforma
