Resonant cavity light-emitting diodes grown by solid source MBE
We report solid source molecular beam epitaxy growth of visible, 650-nm range, resonant cavity light-emitting diodes. Devices operating at red wavelengths utilise an (AlxGa1-x)(y)In1-yP active region and AlxGa1-xAs distributed Bragg reflectors. Components with an emitting window of 84 mum exhibit a record high external quantum efficiency of 6.5% and output power of 2 mW.
