From: Pb(core)/ZnO(shell) nanowires obtained by microwave-assisted method
Structural analysis Pb(core)/ZnO(shell) nanowires. (a, c, e) HAADF-STEM micrograph and (b, d f) BF-STEM micrograph of the Pb(core)/ZnO(shell)-NWs. Internal diameter (Pb-core) is about 4 nm. (d) The ZnO-shell, the FFTs analysis confirms that the shell is ZnO hexagonal wurtzite-type with preferential growth in the [001] direction. (e) Pb can be seen; the inner wire core structure is Pb-cubic (fcc) with preferential growth in the [111] direction.
