HQ grapheneHfSe2 Crystal

Product Name Name: HQ grapheneHfSe2 Crystal Product Overview HfSe2 is a semiconductor with an indirect band gap of ~ 1.1eV. These layers are stacked together through van der Waals interactions and can be stripped off into thin 2D layers. Hafnium diselenide is a group IV transition metal chalcogenide (TMDC). The HfSe2 crystals produced by HQ Graphene have a lateral size of ~ 0.6-0.8cm and are hexagonal, with a metallic appearance. Technical Parameter Purity: 99.995% Size: ~8 mm Color: Gray black Product characteristics Electrical properties:Semiconductor Crystal structure:Hexagonal Unit cell parameters:a = b = 0.3745 nm, c = 0.6160 nm, α = β = 90°, γ = 120° Type:Synthetic Purity:>99.995% Application Fields Hafnium selenide crystals have important applications in nonlinear optics because of their high nonlinear coefficient and excellent optical properties. It can be used to generate and detect electromagnetic waves in the terahertz band, which is very useful in modern communications, imaging and sensor technologies. In middle and far infrared lasers, hafnium selenide crystals can be used as down frequency converters to convert low frequency lasers to high frequency lasers. This property makes it play an important role in the generation of mid-infrared to far-infrared light sources. Hafnium selenide crystals can also be used in the field of photodetectors, especially for high-sensitivity detection in the mid-infrared band. Its high damage resistance threshold and low absorption coefficient make it an ideal detection material. Hafnium selenide crystals are also widely used in terahertz oscillation and detection. For example, it can generate terahertz pulses through the optical rectification effect, and it performs well in terahertz time-domain systems Related Information Link:http://www.hqgraphene.com/HfSe2.php Please e-mail for the detailed characterization data.
