Figure 2. (A-C) SEM images of (A) SiNSs, (B) GeNSs and (C) H2 nanocomposites; (D) TEM image of H2 nanocomposites, (E) HRTEM of H2 nanocomposites; (F) HRTEM image of the dark blue circle in (E), inset is the corresponding fast Fourier transform (FFT) pattern; (G) HRTEM image of the yellow circle in (E), inset is the corresponding fast Fourier transform (FFT) pattern. (H-K) STEM image of the GeNSs/SiNSs composites (H) with its corresponding EDS elemental mapping of (I) O, (J) Si, and (K) Ge elements.
