Web1 day ago · The refractive index of the CLD-1/PMMA film with a thickness of 1 μ m was measured by an ellipsometer (J. A. Woollam, M-2000). When a voltage is not applied, the refractive index of the polymer film is 1.488045, and the thickness of the spin-coated polymer film is 1 μ m.The refractive index varies with voltage as 0.00116/V.
