Controlled growth mechanism of ring-like In(Ga)As quantum Dot pairs on GaAs ring-ring-disk nanostructures templates
The ring-like In(Ga)As quantum dot pairs (QDPs) is prepared on GaAs ring-ring-disk (R-R-D) nanostructures template by droplet epitaxy (DE) method.The surface morphology of GaAs samples are characterized with Scanning Tunneling Microscope (STM), guerlain ideal cologne and studying local controlled growth mechanism of quantum dots (QDs) on GaAs R-R-D
