No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages. An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.
characteristics if gunn diode
0.7 The voltage across a silicon diode when it is forward biased should be greater than or equal (>=) 0.7volts.
forward drop is the same as any other silicon diode, about 0.7V
As that of most power devices power diode are maid from silicon material(because of its wide band gap) . but now days alloy of silicon are used like sic(silicon carbide) by ank
SILICON same as any other diode but with different characteristics
Potential barrier of silicon is 0.7, whereas potential barrier of germanium is 0.3

A germanium diode has a lower forward voltage drop compared to a silicon diode, typically around 0.3V for germanium and 0.7V for silicon. Germanium diodes also have a higher reverse current leakage compared to silicon diodes.
characteristics if gunn diode
A silicon avalanche photo diode is fabricated by the process called impact ionization.
A silicon diode is a tiny electronic component having two terminals, usually a switch or limiting device.
The built is voltage would be lower than silicon diode,more leakage or reverse saturation current,poor thermal stability,high noise and greater conduction in comparison to silicon diodes.
The entire 1N40xx series of power diodes are all silicon. The OA79 small signal diode is germanium.
It is not 'Cutting voltage' but it is Cut-in voltage'. It is the voltage at which the diode turns ON. For silicon it is 0.7v. After reaching 0.7V diode current starts increasing rapidly for little increase in voltage.
the cut in vol for silicon diode is 0.7 where as germaium is around 0.3 because of their construction( the ratio of majority n minority carreirs)
what is the difference between reverse characteristics of zener diode and a practical diode ?
