Abstract Scope |
Nanomultilayers (NMs) are composite coatings with alternating material layers of thicknesses at the nanoscale. The highly tailorable NMs present a wide range of parameters which can be optimized for optical, electrical, magnetic or mechanical applications, for example. In this study, transparent optical nanomultilayers, AlN/SiO₂, TiO₂/SiO₂, and AlN/Al₂O₃, were optimized to yield a 94% average transmittance in the UV/Vis/NIR wavelength range. More interested in their multifunctional coating applications, nanoindentation, micropillar compression, and microtensile tests were performed on the optically optimized systems in order to correlate transmittance and microstructure to the mechanical behavior. Overall, different microstructures were observed depending on the NM configuration, leading to distinct failure behaviors. |
