Question

Arrange the following in terms of increasing dimension of quantum confinement of electrons at nanoscale
• Quantum Dot
• Bulk Material
• Quantum Well
• Quantum Wire Choose the correct answer from the options given below:

• A. D $<$ A $<$ C $<$ B
• B. C $<$ A $<$ B $<$ D
• C. B $<$ C $<$ D $<$ A
• D. A $<$ D $<$ C $<$ B

Hint:

Greater the number of confined dimensions, stronger is the quantum confinement effect: \[ \text{Bulk} < \text{Well} < \text{Wire} < \text{Dot} \]

Answer 1

The Correct Option is D
