Most reports on AlScN thin films grown on Si substrates have focused on textured films, whereas epitaxial AlScN thin films have predominantly been demonstrated on Al2O3 substrates. In this study, we achieved epitaxial growth of AlScN thin films on Si by employing TiN as a buffer layer, and we confirmed the crystalline quality and evaluated the ferroelectric properties.
