Tungsten Selenide WSe2 | MoSe2 Cu2Se 3N 3N5 4N

Description

Tungsten Selenide or Tungsten Diselenide WSe2 CAS 12067-46-8, density 9.32g/cm3, molecular weight 341.76, is insoluble in water. Tungten Diselenide belongs to group V transition metal dihaloalkanes TMDC. WSe2 is a P-type or N-type semiconductor with an indirect band gap of ~1.3ev, and a single layer of WSe2 has a direct band gap. These layers are stacked together by Vander Waals interaction and can be stripped into thin 2D layers. Being Lamellar structured, dry and solid lubricant, WSehas the lowest thermal conductivity with exceptional stability at high temperatures and in high vacuum. Tungsten Selenide thin films for terrestrial photovoltaic is synthesized by Chemical-Vapor-Deposition CVD, which can be for flexible thin film solar cell, or as a sputtering target. Selenide compound find many application as electrolyte material, semiconductor dopant, QLED display, IC field and other material fields etc.

Molybdenum Selenide

MoSe

Molybdenum Selenide MoSe2, gray solid crystalline appearance, layered structure, is an inorganic compound semiconductor of molybdenum and selenium, which is known as group VI transition metal dichalcofemides, CAS 12058-18-3, density 6.0g/cm3, MW 253.86, melting point 1200°C, insoluble in water. Bulk MoSe synthesis and purification involves direct reaction of molybdenum and selenium by chemical vapor transport CVT, singlr crytstal MoSe is produced by scotch tape exfoliation from bulk crystal or by chemical vapor deposition CVD. Molybdenum Selenide MoSe2, narrow band gap of 1.2ev, can not only absorb ultraviolet light but also visible light, it exhibits a wide range of light response and high utilization efficiency of solar light, so it is used as photodetectors and transistors. Molybdenum Selenide's layered nature and higher electrical conductivity gives rise to several interesting applications such as field effect transistors, piezoelectrics, and substrates for self assembly, and also for material modification, lubricant additives, solar cells, energy storage, microelectronics, optoelectronics and high performance photocatalysts. Molybdenum Selenide MoSe2 at Western Minmetals (SC) Corporation with purity of 99.99% 4N can be delivered in form of submicro and nanomicron powder, granule, lump, chunk, blank, bulk crystal and single crystal etc or as customized specification.

Copper Selenide

Cu2Se

Copper Selenide or Dicopper Selenide, Cuprous SelenideCu2Se CAS No 20405-64-5, black cubic crystal, density 6.749, melting point 1113°C, insoluble in water but easily soluble in nitric acid, soluble in sulfuric acid and ammonia. Copper Selenide is prepared in a vacuum quartz seal tube placed in horizontal synthesis furnace. Ligand-stabilized copper selenide (Cu(2-x)Se) nanocrystal is synthesized by a colloidal hot injection process, which readily disperse in water and exhibit strong near-infrared (NIR) optical absorption with a high molar extinction coefficient, it finds application in photothermal therapy, ad for the preparation of group compound semiconductor, cuprous selenide target material, copper-indium-gallium-Selenium CIGS thin film solar cell etc. Copper Selenide CuSe at Western Minmetals (SC) Corporation with purity of 99.99% 4N, 99.999% 5N can be delivered in form of powder, granule, lump, chunk, pill, needle, blank, bulk crystal and single crystal etc or as customized specification.
