AsSe

AsSe is a binary chalcogenide ceramic compound composed of arsenic and selenium, belonging to the family of amorphous and crystalline semiconducting materials. It is primarily used in infrared optics and thermal imaging applications where its transparency in the mid- to far-infrared spectrum is valuable, as well as in specialized photonic and switching devices that exploit its nonlinear optical properties. AsSe is notable for its ability to function across a wide infrared window with minimal absorption, making it preferable to alternative materials like germanium or zinc selenide when operation in specific infrared bands is required, though it is less common than some competing chalcogenide compositions.
