Intrinsic semiconductors are pure, stoichiometric materials that have not been doped with additional compounds in order to modify their electrical conductivity. The band gap of these materials increases as we move from group IV materials like silicon and germanium to III-V (GaAs etc) and I

Energy bands and band gaps in materials
Isolated atoms have energy levels corresponding to s, p, d, f orbitals etc. However, as we bring atoms close together we have to worry about overlap leading to multiple electrons having the same quantum numbers. This would violate pauli exclusion principle!! Instead, we have to slightly ch
