SCI Engineered Materials™ is pleased to offer a wide range of single-crystal substrates for making high-quality thin films. We are a global supplier of high-quality substrates and if you don’t see your needed substrate listed in the following pages, please request a quote, chances are we can meet all your substrate needs. Typically used in CVD and E-Beam processes, substrates can be used for epitaxial growth, prototyping thin-films, or utilized for each of their unique crystal lattice structures. Films can be transferred, or the substrate-film utilized itself as a specialized component in itself.

Substrates are important in the growth of single-crystalline materials as they serve as the crystal-structure blueprint for the coatings that are deposited upon them. Smoothness, as well as particular orientations are important for coatings to function properly.
