Author(s): Nicholas A. Pike, Ruth Pachter, William J. Kennedy, and Nicholas Glavin We report on an investigation of the structural and ferroelectric properties of Al 1 – x Sc x N , Sc y Ga x N ( x + y = 1 ) , and quaternary Al 1 – x – y Sc y Ga x N alloys using density functional theory (DFT) calculations. The calculated spontaneous polarization ( P sp ) and coercive field ( E c ) values for the Al 1 – x Sc x N and Sc y G… [Phys. Rev. B 112, 085204] Published Fri Aug 08, 2025
