Class 23: Confinement and Quantization
... For nearly free electrons, the extent of confinement is the extent of the solid, and is in the order of meters. Therefore the value of „ ‟ is relatively large in this case and since it is in the denominator, it causes the adjacent values of to be closely spaced. This in turn causes the allowed value ...
