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 utilize method its fullest potential. In this paper, heterostructures composed hBN-capped molybdenum ditelluride (MoTe2) disulfide (MoS2) are optically modified with continuous wave laser. The process simultaneously thins MoS2 induces clustering tellurium atoms from ablated MoTe2. These structural changes result in significant enhancements properties, including 43-fold increase photoluminescence transformation heterojunction into an anti-ambipolar transistor. findings highlight previously unutilized pathway tune heterostructure applications novel electronics optoelectronics.

Triangular metal chalcogenide clusters of the form [M3Q7L3]An (M = Mo or W; Q S Se; L iBu2NCS2-, (CF3CH2)2NCS2-, iBu2NCSe2-, iBu2PS2-; An Cl- I-) have been investigated as molecular analogues layered dichalcogenide (MX2) H2-evolution catalysts. These evaluated for their relative H2-evolving ability under a common photolysis protocol implementing [Ru(bpy)3]2+ chromophore and Et3N sacrificial electron donor. With M constant with supporting ligand, an all-sulfide core enable greater H2-TON than all-selenide core. A more active catalyst is produced by [Mo3S7(S2CNiBu2)3]+I- its W3 analogue same sulfide composition dithiocarbamate ligands. Dichalcogenocarbamate ligands provide catalysts dialkyldithiophosphate ligated clusters, within dichalcogenocarbamate set, H2-turnovers correlate more-electron-donating (i.e., iBu2NCS2- > (CF3CH2)2NCS2- iBu2NCSe2-). Cluster cations counteranion are very similar in activity levels to identical I-, ruling out any significant interfering effect I- upon transfer relay between catalyst. In aggregate, observations consistent mechanism H2 evolution that involves reductive extrusion from hydride intermediate.
