Question

One dimensional nanostructure amongst the following is:

पर्याय

• Nanoparticles

• Nanotubes

• Nanofilms

• Nanorods

Answer 1

Nanotubes and nanorods

Explanation:

One-dimensional (1D) nanostructures have two dimensions restricted to the nanoscale (between 1 and 100 nm), while electrons can move freely along one remaining large dimension. Both nanotubes (hollow tubes) and nanorods (solid cylinders) fit this definition perfectly. In contrast, nanoparticles are 0D (all dimensions nanoscale), and nanofilms are 2D (only thickness is nanoscale).
