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 (\(1-100 \text{ nm}\)). 
Step 3: Detailed Explanation: 
In a one-dimensional (1D) nanostructure, two dimensions are in the nanoscale (width and thickness \(< 100 \text{ nm}\)), while the third dimension (length) can be significantly larger. 
Common examples include Nanowires and Nanorods. 
These structures have unique electronic and optical properties because electron movement is restricted in two directions but free in one. 
Step 4: Final Answer: A typical example of a 1D nanostructure is a Nanowire.
