Few-layer tungsten disulfidePowder (with original solution)

Product Overview
Few Layers WS₂ Powder consists of tungsten disulfide nanosheets with a precisely controlled 1-10 layer structure. This transition metal dichalcogenide features the characteristic S-W-S sandwich configuration where tungsten atoms are covalently bonded between sulfur layers in a hexagonal arrangement. Prepared through lithium intercalation methodology, this material undergoes ultrasonic exfoliation and freeze-drying processes to maintain a 1T-2H hybrid crystal structure with approximately 60% 1T phase content (batch-dependent).
