Physical properties of 1-D ZnO-based nanostructures

Nanotechnology refers to the design, synthesis and applications of nanostructures and nanomaterials. When a structure undergoes miniaturisation to the nanometre scale, it may start exhibiting new physical properties or phenomena. One-dimensional (1-D) nanostructures have attracted immense attent...
