Fig. 1From: MBE Growth of AlN Nanowires on Si Substrates by Aluminizing Nucleation a A schematic illustration of the aluminization process. Al flux reacts with β-Si3N4 to form AlN islands as nuclei for AlN NW growth. AFM images of the substrates aluminized at (b) 850 °C and (c) 950 °CBack to article page
