Therefore, for understanding electron energies in Si or Ge crystal, we need to consider the changes in the energies of the electrons in the outermost orbit only. The overlap (or interaction) will be more felt by the electrons in the outermost orbit while the inner orbit or core electron energies may remain unaffected. However, in a crystal, the atoms are close to each other (2 Å to 3 Å) and therefore the electrons interact with each other and also with the neighbouring atomic cores. The electron energy will be same if all the atoms are isolated, i.e., separated from each other by a large distance. Electrons of each atom will have discrete energies in different orbits. *This information is for general informational purposes only, we will not be liable for any loss or damage caused by the above information.Read the following text and answer the following questions on the basis of the same:Band theory of solid:Consider that the Si or Ge crystal contains N atoms.
