Bismuth is an example of a diamagnetic material, yet this is not the behavior we would expect from the element's electron configuration ... p and f orbitals. Typically, diamagnetic materials ...
Owing to the confinement, the electron motion is quantized, and because QDs can be incorporated into large semiconductor devices, they can in principle be easily addressed through external fields.
Concept of atomic orbitals as one-electron wave functions: Variation of and 2 with r for 1s and 2s orbitals; various quantum numbers (principal, angular momentum, and magnetic quantum numbers ...
