{"product_id":"hq-graphene-gas-crystal","title":"HQ graphene GaS Crystal","description":"\u003cp\u003eProduct Name Name: HQ graphene GaS Crystal Product Overview GaS (beta phase) is a semiconductor with an indirect band gap of ~2.6 eV. The layers are stacked together via van der Waals interactions and can be exfoliated into thin 2D layers. α-GaS belongs to the group-13 post-transition metal monochalcogenides. The Gallium sulfide crystals produced at HQ Graphene have a typical lateral size of ~0.6-0.8 cm. The crystals are yellow colored and transparent. Technical Parameter Purity: 99.995% Size:6-8 mm Color: Canary yellow Product characteristics Electrical properties:Topological Insulator, Thermoelectric material Crystal structure:Hexagonal Unit cell parameters:a = b = 0.438 nm, c = 3.050 nm, α = β = 90°, γ = 120° Type:Synthetic Purity:\u0026gt;99.995% Application Fields In the semiconductor field: Manufacturing photodetectors: Gallium sulfide crystals have a good response to specific wavelengths of light and can be used to manufacture high-performance photodetectors. For example, in optical fiber communication systems, gallium sulfide crystal photodetectors can convert optical signals into electrical signals, enabling high-speed, sensitive optical communication. Solar cell: can be used as solar cell absorption layer material. For example, in thin-film solar cells, gallium sulfide crystals help to improve the photoelectric conversion efficiency of the cell. In the field of optics: Nonlinear optical devices: Due to their nonlinear optical properties, they can be used to manufacture nonlinear optical devices such as frequency doublers and mixers. For example, in laser systems, gallium sulfide crystals can achieve the conversion and modulation of laser frequencies. Light-emitting diode (LED) : As a light-emitting material, used to manufacture efficient light-emitting diodes. For example, in some special purpose leds, gallium sulfide crystals can emit specific wavelengths of light. In the field of sensors: Gas sensor: Sensitive to certain gases, can be used to detect the concentration of a specific gas. For example, it is used to detect harmful gases in the environment, such as hydrogen sulfide.
