Source sentences:
text: When a bond is broken, a free electron, along with a free hole, results, i.e., the electron possesses enough thermal energy to cross the bandgap to the conduction band, leaving behind a hole in the valence band.
text: These electrons will leave after holes within the valence band.
text: Excitons are formed when an electron that has absorbed a photon and left a hole in its place in the valence band does not move away from the hole but, held back by Coulomb attraction, remains near the hole.
text: When the electrons leave a hole, then space will be attracted by other electrons.
text: These electrons are then excited to conduction orbitals (3), leaving holes behind in the valence band (2) creating a charge carrier pair or exciton.
