WS2 powder 0.88μm

Product Name

^{Name: WS2 powder 0.88um}

Product Overview

^{Tungsten disulfide (WS2) is a type of transition metal sulfide (TMDC) with a graphene like layered structure, where the layers are stacked together by weak van der Waals forces. Single layer WS2 is composed of three layers of atoms, with the atomic planes of W and S arranged in a hexagonal array. The W atoms are sandwiched between the two layers of S atoms, forming an S-W-S atomic layer structure with a "sandwich" structure. Multi layer or block WS2 is composed of single layers stacked together. Depending on the stacking method of the single layers, WS2 has three crystal structures: 1T, 2H, and 3R.}

^{The synthesis methods of WS2 are mainly divided into two categories: "top-down" stripping method and "bottom-up" method. The "top-down" exfoliation method includes micro mechanical exfoliation, liquid-phase exfoliation, and lithium-ion intercalation, mainly using physical means to exfoliate the bulk WS2 into a single-layer or few layer layered structure. The "bottom-up" method includes chemical vapor deposition, hydrothermal method, and high-temperature thermal decomposition method, mainly using chemical means to grow atoms and molecules into nanoscale thin films and granular WS2 under certain environmental conditions.}
