Which of the following nanomaterials has one dimension < 100 nm?
Options
- AQuantum dots
- BNanorings
- CThin films
- DNanowires
Correct answer
C. Thin films
Step-by-step solution
Nanomaterials are classified based on the number of dimensions that lie in the nanoscale range ( 1 to 100 nm). Zero-dimensional (0D) nanomaterials have all three dimensions in the nanoscale. Examples include quantum dots and nanoparticles. One-dimensional (1D) nanomaterials have two dimensions in the nanoscale. Examples include nanowires and nanotubes. Two-dimensional (2D) nanomaterials have exactly one dimension in the nanoscale. Examples include thin films, graphene, and nanosheets. Three-dimensional (3D) nanomat
