Optically Pumped AlGaN Double Heterostructure Deep-UV Laser by Molecular Beam Homoepitaxy: Mirror Imperfections and Cavity Loss

Len van Deurzen, Ryan Page, Vladimir Protasenko +3

We demonstrate the first optically pumped sub-300 nm UV laser structures grown by plasma-assisted molecular beam epitaxy on single-crystal bulk AlN. The edge-emitting laser structu…

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…
