{"product_id":"hq-graphene-ws2-tungsten-disulfide","title":"HQ graphene WS2 (Tungsten Disulfide)","description":"\u003cp\u003eProduct Name Name: HQ graphene 2H-WS2 (Tungsten Disulfide) Product Overview 2H-WS2 is a semiconductor with an indirect band gap of ~1.3 eV. Monolayer 2H-WS2 has a direct band gap. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Tungsten Disulfide belongs to the group-VI transition metal dichalcogenides (TMDC). The 2H phase WS2 crystals produced at HQ Graphene have a typical lateral size of ~0.8-1 cm, are hexagonal shaped and have a metallic appearance. The 2H WS2 is n-type semiconductor, having a typical charge carrier density of ~1014cm-3 at room temperature. Technical Parameter Purity: 99.995% Size: ~10 mm Color: Silver gray Product characteristics Electrical properties:Semiconductor Crystal structure:Hexagonal Type:Synthetic Purity:\u0026gt;99.995% Application Fields In the field of lubrication: Solid lubricant: Due to its layered structure and low coefficient of friction, it can be used as a high-performance solid lubricant.
