Abstract :
InAsN/GaAsN quantum dots were grown on GaAs substrate by MBE. Structure and optical properties of single layer and multilayer dots were characterized and analyzed by photoluminescence and atomic force microscopy. High density InAsN dot (1.1×1011 cm-2) is achieved. Multilayer is found to increase the emission wavelength to 1120nm with the effect of electron state couple between dots in different layers.
