ZnO 2 hollow nanospheres and nanotubes were synthesized via hydrothermal treatment of ZnO submicron-sized powder in 20vol.% H 2 O 2 aqueous solution at 120°C for 6h, and ZnO with similar hollow nanostructures could be obtained by thermal decomposition of the hydrothermally-synthesized ZnO 2 hollow nanospheres and nanotubes in air at 200°C for 6h. The possible formation...
The microstructure of n-type Bi 2 (Te 0.95 Se 0.05 ) 3 thermoelectric compound fabricated by gas atomization and hot extrusion was analyzed using transmission electron microscopy, particularly by high resolution transmission electron microscopy on layered structures. The sequence of the five atomic layers, i.e. Te–Bi–Te–Bi–Te, corresponded to one quintet along c-axis...
