SUMMARY
An energy band is defined as a continuous distribution of similar energy levels that arises due to the close proximity of atoms in solids. As atoms come closer together, their wavefunctions overlap, causing discrete energy levels to lose degeneracy and spread out into bands. This phenomenon is a direct result of the periodic arrangement of atoms and the overlapping wavefunctions, which allows electrons to occupy a range of energy states within these bands. Understanding energy bands is crucial for grasping the electronic properties of materials.
