Question

Match List-I with List-II

List-I (Dimensions)	List-II (Materials shape)
(A) Quantum dot	(I) 3-dimensional
(B) Quantum Wire	(II) 2-dimensional
(C) Quantum Well	(III) 1-dimensional
(D) Micro-materials	(IV) 0-dimensional

Choose the correct answer from the options given below:

• (A) - (II), (B) - (I), (C) - (III), (D) - (IV)
• (A) - (III), (B) - (II), (C) - (I), (D) - (IV)
• (A) - (IV), (B) - (III), (C) - (II), (D) - (I)
• (A) - (I), (B) - (IV), (C) - (II), (D) - (III)

Hint:

Visualize quantum materials: Quantum dots are confined in all directions (0D), wires in two (1D), and wells in one (2D), while micro-materials are unconstrained in 3D.

Answer 1

The Correct Option is C

- (A) Quantum dots are 0-dimensional due to their confinement in all spatial directions.
- (B) Quantum wires are 1-dimensional due to confinement in two dimensions.
- (C) Quantum wells are 2-dimensional with confinement in one direction.
- (D) Micro-materials have bulk 3-dimensional properties.
