The ratio of the number of emitted photoelectrons to the number of incident photons. 3, record 1, English, - quantum%20efficiency
Record number: 1, Textual support number: 1 CONT
The quantum efficiency may be given either as a function of wavelength or as energy. If all photons of a certain wavelength are absorbed and the resulting minority carriers are collected, then the quantum efficiency at that particular wavelength is unity. The quantum efficiency for photons with energy below the band gap is zero. 4, record 1, English, - quantum%20efficiency

Le rendement quantique (Φ) d'un processus induit par le rayonnement est égal au nombre de fois qu'un évènement donné arrive divisé par le nombre de photons absorbé par le système. L'évènement en question est souvent une réaction chimique. 3, record 1, French, - rendement%20quantique
