Figure 3From: NH3 molecular doping of silicon nanowires grown along the [112], [110], [001], and [111] orientationsStructures of the adsorption of NH 3 on SiNWs. Viewed from top (upper) and sidewalls other than the {110} facetside (lower): (a, b, c) the SiNWs grown along the [112], [110], and [001] directions, respectively. Yellow, white, and blue spheres indicate Si, H, and N atoms, respectively.Back to article page
