Multilayer structures can be fabricated using several techniques, including: - Layer-by-layer (LbL) assembly: This involves sequential adsorption of polyelectrolytes or nanoparticles to build up layers. - Chemical vapor deposition (CVD): A process where chemical precursors react on a substrate to form thin films. - Physical vapor deposition (PVD): Involves the physical transfer of material from a source to the substrate, forming thin layers.
