Tungsten Selenide (WSe2) Evaporation Materials Description

Stanford Advanced Materials (SAM) specialises in the production of high-purity tungsten selenide (WSe2) evaporation materials for use in semiconductor, CVD and PVD display as well as optical applications. The development, manufacturing and analysis teams have worked together to produce tungsten selenide (WSe2) evaporation materials that meet defined quality specifications.

Tungsten Element Introduction

Tungsten (chemical symbol: W, atomic number: 74) is a d-block element from group 6 and period 6 with an atomic mass of 183.84. Its electrons are distributed as 2, 8, 18, 32, 12 and 2 in the respective shells. The electron configuration is [Xe] 4f14 5d4 6s2. The Bohr radius is 139 pm and the van der Waals radius is 210 pm. Tungsten was discovered in 1781 by Torbern Bergman and first isolated in 1783 by Juan José Elhuyar and Fausto Elhuyar. In elemental form it shows a grey-white, lustrous appearance. Tungsten has the highest melting point of all metallic elements. Its density is comparable to that of uranium or gold and is approximately 1.7 times that of lead. Tungsten alloys are used for manufacturing filaments and targets in X-ray tubes. It occurs in the minerals scheelite (CaWO4) and wolframite ((Fe, Mn)WO4).

Tungsten Selenide (WSe2) Evaporation Materials Applications

Tungsten selenide (WSe2) evaporation materials exhibit properties that make them useful in several technological areas. In electronics and optoelectronics they are employed in field-effect transistors (FETs) and photodetectors due to high charge carrier mobility and photosensitivity. They are used as a catalyst in the hydrogen evolution reaction (HER) for energy storage applications. They show potential for use in lithium-ion batteries. Their suitability for solar cells, light-emitting devices and photocatalysis extends applications in photovoltaics and environmental remediation. They provide corrosion resistance and solid lubrication properties, which makes them applicable in coatings and lubricants. Their sensor capabilities support gas detection and their biocompatibility facilitates use in biomedical devices.
