Linked from
The 15 pages that link to Electron–hole pair, each with the reason it gives.
Band gapRelated: Promoting an electron across the gap creates this pair.
ExcitonNarrower topic: Their attraction binds the pair into an exciton.
Fermi levelRelated: Thermal generation of these pairs shifts occupations around the Fermi level.
PhotoconductivityBroader topic: Photons can create these paired carriers, increasing conductivity.
ElectroluminescenceRelated: Their recombination releases energy that can emerge as light.
Laser diodeRelated: Their recombination in the active region can release photons.
Valence and conduction bandsRelated: Excitation across the gap creates both charge carriers.
