HQ graphene WSe2 Crystal

Product Name Name: HQ graphene WSe2 Product Overview WSe2 is a semiconductor with an indirect band gap of ~1.3 eV, monolayer WSe2 has a direct band gap. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. Tungsten Diselenide belongs to the group-VI transition metal dichalcogenides (TMDC). The WSe2 crystals produced at HQ Graphene have a typical lateral size of ~0.8-1 cm, are hexagonal shaped and have a metallic appearance. We produce both n-type and p-type WSe2, having typical charge carrier densities of ~1015cm-3 at room temperature. Technical Parameter Purity: 99.995% Size: ~6-8mm Color: Silver gray Product characteristics Electrical properties:Semiconductor Crystal structure:Hexagonal Type:Synthetic Purity:>99.995% Application Fields In the field of electronics: Field-effect transistors (Fets) : Because of their excellent electrical properties, they can be used to manufacture high-performance, low-power Fets. For example, in the next generation of nanoelectronic devices, smaller sizes and better performance can be achieved. Integrated circuit: It is expected to become a key component in the integrated circuit in the future, improving the integration and computing speed of the chip. In the energy sector: Solar cells: can be used as the absorption layer material of solar cells to improve the photoelectric conversion efficiency. For example, in new thin-film solar cells, it helps to enhance the absorption of sunlight and charge transport. Lithium-ion battery: As the electrode material of lithium-ion battery, it shows good electrochemical performance and cycle stability. In the field of catalysis: Hydrogen evolution (HER) catalysis: In the electrolysis of water to produce hydrogen, it is a potential catalyst for hydrogen evolution reaction, which can reduce the energy required for the reaction and improve the efficiency of hydrogen production.
