It is one junction i.e. P-N junction diode.
photo diode donot work for long distance photo diode act as a receiver
another name for diode is "pn" junction.
when the p-n junction is heavily doped p-n junction diode has very sharp breakdown voltage.
Its schotlky diode. schotlky diode is metal semi conducter junction. It has fast switchng speed. The cutting voltage of schotlky diode is about 0.2 volts.
It is one junction i.e. P-N junction diode.
a diode can be make using p-n junction....form a p junction n form a n junction...and after joining them u cn make a p-n junction diode....for making a diode u ll ve to face doping problems

Schottky Diode
diode is unipolar
another name for diode is "pn" junction.
Schottky diode
zener diode
cutoff
A Photo-diode is used to receive light. whereas the L.E.D. is a Light Emitting Diode.
Zener diode is heavily doped pn junction diode.
The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
