Abstract—: The principal possibility of synthesis of InGaN nanostructures of branched morphology (“nanoflowers”) by molecular beam epitaxy on the surface of a silicon substrate has been demonstrated. The results of morphological studies have shown that the development of the morphology of InGaN nanostructures occurs in several stages even when maintaining a constant substrate temperature. The grown structures exhibit a photoluminescence line in a wide wavelength range from 450 to 950 nm at room temperature.
