QUE SIGNIFIE PHOTOCURRENT EN ANGLAIS
Photocurrent
Photocourant est le courant qui traverse un dispositif photosensible, tel qu'une photodiode, en raison de l'exposition à une puissance rayonnante. Le photocourant peut se produire en raison de l'effet photoélectrique, photo-émissif ou photovoltaïque. Le photocourant peut être amélioré par un gain interne provoqué par l'interaction entre les ions et les photons sous l'influence des champs appliqués, comme par exemple dans une photodiode d'avalanche. Lorsqu'un rayonnement approprié est utilisé, le courant photoélectrique est directement proportionnel à l'intensité du rayonnement.
définition de photocurrent dans le dictionnaire anglais
La définition de photocourant dans le dictionnaire est un courant électrique produit par le rayonnement électromagnétique dans l'effet photoélectrique, l'effet photovoltaïque, ou la photoconductivité.
