AlScN (Alminium scandium nitride) is attracting attention for next generation of ferroelctric material with its large polarization. Recently, application for electro-optic devices is considered and control of polarization is researched. In this study, with introducing thin AlSc seed layer in AlScN deposition, control of polarization without switching by voltage is achieved.
