Optical thin film for meta-surface and meta-optical device including the same

An optical thin film includes a support layer and a dielectric layer on the support layer. The dielectric layer has a refractive index greater than that of the support layer. The dielectric layer includes a compound ADX, which includes a Group 3 element A, a Group 5 element D, and an element X havin...

Beschreibung
Zusammenfassung:	An optical thin film includes a support layer and a dielectric layer on the support layer. The dielectric layer has a refractive index greater than that of the support layer. The dielectric layer includes a compound ADX, which includes a Group 3 element A, a Group 5 element D, and an element X having an atomic weight smaller than an atomic weight of A or D. The optical thin film may exhibit light transmission having a high refractive index and low absorptivity.
