Aperture-Controlled All-Dielectric Structural Color Pixels

This cover page illustration depicts microfabricated structures that create interference-based structural color pixels.
This technology utilizes varied aperture-controlled physical deposition rates of low-temperature SiO2 inside hollow cavities, resulting in thin films with controlled thickness. This thickness defines the wavelengths of constructive interference, giving rise to vibrant colors. (ACS Appl. Mater. Interfaces 2023, 15, 27, 33056-33064)
