We report on our results of the numerical simulations of a quantum dot (quantum wire)-quantum well cascade structure. Experimental work on the quantum dot structure was recently reported in the literature. For parameters of such a structure, the calculated emission spectra has a single peak for up to four electrons in the dot. The width of the emission line is found to be due to long-range in-plane disorder, resulting mainly due to fluctuations of the height of the dots. © 2003 American Institute of Physics.

    Nanowires, nanotubes, and nanodots (quantum dots) are nanomaterials (NMTs). While nanodots are miniaturized nanowires, nanotubes are hollow nanowires. A universal model for basic science of the synthesis and characteristics of NMTs must be established. To achieve this goal, a general hypothesis...
