TEM image of Mo NW and bundles. (a) TEM of small MoSI NW bundle. (b) High resolution TEM image of Mo NW with a diameter of approximately 5 nm. The arrows point at the grain boundaries where NW can be flexible to elastic structural deformation (c) and (d) show TEM images for large diameter Mo NWs (>15 nm) with significant surface roughness. The pore formation is clearly visible as hollow voids of various sizes that are incorporated in the bulk and the surface structures.
