Abstract

GaInAs quantum disks are fabricated by wet chemical etching from a GaInAs/GaAs near‐surface quantum well using self‐organized InP islands as an etch mask. InP islands are formed in coherent Stranski–Krastanow growth mode by metalorganic vapor phase epitaxy. The free‐standing GaInAs/GaAs columns, produced by a three‐step etching process, are overgrown at 550 °C. The luminescence efficiency per emitting area from the regrown quantum disks is one order of magnitude larger than that from a regrown reference quantum well.
