The nanosheet morphology of the pristine GO was well preserved in the resultant N,P-graphene-1 without noticeable residues of the solid precursors, as shown in the scanning electron microscope (SEM) and transmission electron microscopy (TEM) images.
As shown in the scanning electron microscopy (SEM) image of Fig. 1a, triangular crystals were uniformly distributed on a SiO2/Si substrate over a large area.
As shown in the scanning electron microscopy (SEM) images (Fig. 2a, b and Supplementary Fig. 1), well-aligned tapering nanowire arrays with diameters of ~100 200 nm and lengths up to 2 μm are uniformly distributed on the carbon paper.
The CNTs in this study are mainly multiwalled CNTs, as shown in the transmission electron microscope (TEM) image (Fig. 1f).
The Ge NWs possessed a core-shell structure, as shown in the transmission electron microscopy (TEM) image in Figure 1c.
As shown in the scanning electron microscope (SEM) graphy (Fig. 3), the Cellu@Fe3O4 has an average diameter of around 29.7 nm and displays uniform structure and morphology.
As shown in the scanning electron microscope (SEM) image in Fig. 2a, the micropillars are in diameter of ~3 μm and height of 7.75 μm, with very smooth sidewalls.
As shown in the scanning electron microscopy (SEM) images in Figure 4c,d,e, the number of CNTs synthesized at a specific location can be controlled by designing the diameter of the nanostencil aperture.
Various nanophase separation technologies for P3HT PCBM systems have been well developed, including thermal annealing [29, 31, 34, 35, 38, 39] and solvent annealing [39, 40] as shown in the transmission electron microscopy (TEM) images in Fig. 1.
