On the Surface Hardening of Zinc Sulfide Windows by Gallium Sulfide
MaterialsThis study examines the effect of gallium doping on the phase transformation, transmission, and hardness of commercial multispectral-grade ZnS specimens exposed to Ga2S3 vapor. Using secondary ion mass spectrometry, we show that Ga diffusion extends into the subsurface down to several tens of microns.

Universal Strategy for Phase‐Selective Synthesis of Monolayer TMDs via Colloidal Chemistry
Advanced Materials, EarlyView.ABSTRACT Colloidal synthesis of monolayer transition metal dichalcogenides (TMDs) remains challenging regarding uniform size, thickness, and crystalline phase. While significant progress has been made in phase engineering, a unified chemical strategy for on‐demand selection of both 2H and 1T′ phases across multiple TMD systems within a single chemical ...
