Germanium Sulfide

Germanium Sulfide or Germanium Disulfide GeS₂, white powder, orthorhombic structure, density: 2.19 g/cm³ , melting point 800°C, molecular mass 136.77, CAS No. 145114-13-2, is a compound of Germanium and Sulfur. Dry Germanium Sulfide is stable in air. Germanium monosulfide can only be prepared from weak acidic or alkaline solution, which will dissolve again when the acidity increases. It can also react with hydrogen chloride and decompose at room temperature. High purity Germanium Sulfide GeS₂ 99.999%, 99.9999% 5N 6N purity, reddish-yellow, amorphous or rhomb crystal and its related compounds are synthesized by Chemical Vapor Deposition (CVD) process at low temperatures and pressures, which has great utility in solid electrolyte memory elements and other electronic devices. Germanium Sulfide GeS₂at Western Minmetals (SC) Corporation with purity of 99.99% 4N, 99.999% 5N can be delivered in form of powder, granule, lump, chunk, blank, bulk crystal and single crystal etc or as customized specification.

Molybdenum Sulfide

Molybdenum Sulfide or Molybdenum Disulfide MoS₂, dark gray with silver gray metallic luster and odorless, CAS 1317-33-5, MW 160.07, density 4.8g/cm³, melting point 1185°C, is hexagonal crystal system. It is soluble in hot sulfuric acid and aquaregia, but insoluble in water, concentrated sulfuric acid and dilute acid. Molybdenum Sulfide MoS2 is both N-type and P-type semiconductor with an indirect band gap of 1.2 eV, and monolayer MoS₂ has a band gap of ~1.9eV. Molybdenum Sulfide MoS₂ is the most famous of the single layer group-VI transition metal dichalcogenide TMD family. MoS2 has been used in bulk for many years as a solid state lubricant, this is due to its low coefficient of friction in addition to its high chemical and thermal stability. But as a new two-dimensional semiconductor material, molybdenum disulfide crystal is playing an increasingly important role in semi monolayer conductor field. When MoS₂ transforms from bulk to two-dimensional semiconductor by Chemical vapor deposition CVD, the band structure changes from indirect band gap to direct band gap, and the band gap width is about 1.9ev. There are more applications in the field of semiconductor devices, photoelectric field, photodetector and transistor etc. Molybdenum Sulfide MoS₂ at Western Minmetals (SC) Corporation with purity of 99.99% 4N in powder, granule, lump, chunk, bulk crystal and single crystal etc is available or as customized specification, with package of polyethylene bottle or composite bag.
