These are nanostructures where electrons are confined in one, two, or three dimensions, respectively.
- Quantum Wells: Electrons are confined in one dimension, allowing movement in two dimensions. - Quantum Wires: Electrons are confined in two dimensions, allowing movement in one dimension. - Quantum Dots: Electrons are confined in all three dimensions, making them zero-dimensional.
These structures have unique electronic and optical properties, which can be tailored for specific applications in optoelectronics and photonics.
