Question

Write example of one dimensional nanostructure of size less than 100 nm.

Hint:

0D = all dimensions<100nm (e.g. quantum dots).
1D = two dimensions<100nm (e.g. nanowires).
2D = one dimension<100nm (e.g. thin films/graphene).

Answer 1

Step 1: Understanding the Concept:
Nanostructures are classified by the number of dimensions that are NOT in the nanoscale (1-100 nm).
In a one-dimensional (1D) nanostructure, two dimensions are in the nanoscale, while one dimension is outside it (usually longer).
Step 2: Detailed Explanation:
One-dimensional nanostructures are those where electrons are confined in two directions and free to move in only one direction.
Common examples include:
1. Nanowires: Long, wire-like structures with diameters less than 100 nm.
2. Nanorods: Similar to nanowires but typically shorter in length.
3. Carbon Nanotubes (CNTs) are also often considered 1D structures.
Step 3: Final Answer:
Examples of 1D nanostructures are nanowires and nanorods.
