Heterostructures of AlGaN with multiple quantum wells were grown by MOVPE on semipolar (20-21) bulk AlN substrates. Smooth epitaxial surfaces with excellent heterostructure interfaces were demonstrated. Luminescence from the AlGaN multiple quantum wells emitting at ? = 237nm show a substantial degree of polarization of about 35% as determined by low-temperature photoluminescence measurements.??
