Epitaxial Sc $_{x}$ Al $_{1 - x}$ N on GaN is a High K Dielectric

Joseph Casamento, Hyunjea Lee, Takuya Maeda +7

Epitaxial Sc $_{x}$ Al $_{1 - x}$ N thin films of ~100 nm thickness grown on metal polar GaN exhibit significantly enhanced relative dielectric permittivity ( $ε_{r}$ ) values relative to AlN.…

Ferroelectricity in Polar ScAlN/GaN Epitaxial Semiconductor Heterostructures

Joseph Casamento, Ved Gund, Hyunjea Lee +11

Room temperature ferroelectricity is observed in lattice-matched ~18% ScAlN/GaN heterostructures grown by molecular beam epitaxy on single-crystal GaN substrates. The epitaxial fil…
