photodiode!!!!!!

hallo every body
i want any information about photodiodes
and i thank u beforehand
bye
abo jako :roll: :roll:

You dont really mention what info you want...whats the proje4ct, the application?
There is plenty of information on the internet about these. I typed photodiode into yahoo search engine and found tons of info.

i want only info about how it work and what it consists of ?

:lol:
Well, consist of a simple PN junction in Si for vulgaris(normal) one or other compounds like GaAs for high-speed/high-sensitivity one.
How it work, the light that enter into semiconductor will generate electrons-gaps pairs based on photons energy. Only electrons-gaps generated into depleted area of junction will be moved by the electric field present in this area and will sum the photo-current.
Usually a photodiode is used in reverse polarization for light sensing, and in direct polarization for converting light energy into voltage-current.
This is the basic about photodiodes.

thanks for response but i want more complex information
with photos and more explain
and thanks for all again

maybe you chould google a bit
