Tungsten diselenide is an inorganic compound with the formula WSe 2. [6] . The compound adopts a hexagonal crystalline structure similar to molybdenum disulfide. The tungsten atoms are covalently bonded to six selenium ligands in a trigonal prismatic coordination sphere while each selenium is bonded to three tungsten atoms in a pyramidal geometry.

Mar 27, 2021 · Tin (Sn)-based perovskites with favorable optoelectronic properties and ideal bandgaps have emerged as promising alternatives to toxic lead (Pb)-based perovskites for photovoltaic applications. However, it is challenging to obtain high-quality Sn-based perovskite films by solution process.

WSe2 is a very stable semiconductor in the group-VI transition metal dichalcogenides. Block: Length <= 1.4 m (by several pieces construction) Width <= 12 inch, Thickness >= 1mm. Tungsten Selenide (WSe2) is commonly used in electronic industries and produced by hot press technique.

Bulk tungsten diselenide (WSe 2), CAS number 12067-46-8, has a high absorption coefficient, high photostability, and a band-gap of 1.2 eV. It is an indirect band-gap semiconducting material that can be both n- and p-doped.

WSe 2 is one of the most important two-dimensional semiconducting material. We first deliver a brief introduction of its first isolation from 3D bulk material and basic crystalline structure.

WSe₂ thin films were fabricated by one-step method using RF sputtering method. Synchrotron-based XRD and PL spectroscopy were employed to reveal detailed structural and optical properties. WSe2 thin films show significant violet emission …
