Thanks for achieving out to Thorlabs, we have been hunting into this concept and I might be in touch with you to Permit you know how the conversation progresses.
The coefficient of thermal growth (CTE) describes a cloth’s inclination to expand or agreement having a transform in temperature. A good CTE would describe a material that expands with raises in temperature, in addition to a unfavorable CTE describes a cloth that contracts with raises in temperature. Precisely, the coefficient of linear thermal expansion (

Moreover, you can examine numerous structural parameters of polycrystalline ZnSe skinny films with diverse thicknesses such as the dislocation density (
It's also utilized as infrared laser acquire medium and being an infrared optical substance. ZnSe activated with tellurium is Utilized in x-ray and gamma ray detectors as being a scintillator. [nine]
Superior chemical stability:ZnSe is highly chemically secure, that makes it immune to corrosion and degradation in severe environments.

tab previously mentioned. Should you have questions on a substrate not described on this web page, please contact Tech Support.
Zinc selenide would be the inorganic compound with the components ZnSe. This is a lemon-yellow strong although most samples Have got a duller shade because of the consequences of oxidation.
Determine six. Direct optical band hole willpower by Tauc relation of as-deposited ZnSe movies at a variety of thickness deposited on glass substrate.
