WebWith a high refractive index Ta2O5 along with Al2O3 makes for an excellent stack as an anti-reflective coating. Both films can easily be grown with the same ALD tool either individually or sequentially. HfO2 ALD is an alternative material solution to Al2O3 ALD as field effect passivation layer. WebJan 29, 2024 · The measured transmittance spectra were studied based on the Swanepoel method, whose results also yielded to the estimation of the film thickness and the refractive index. Finally, Ta2O5 thin films were characterized by AFM measurements and multifractal analyses for an accurate description of the 3-D surface microtexture features.
