What is the use of crystal detector in electronics?
A crystal detector is a diode, often used in non-powered radio receivers. It conducts at a much lower voltage than a typical silicon diode, making it easier to generate the signal amplitude required from the tuning circuit.
What is a substitute for a germanium diode?
There is no exact substitute for a germanium diode, except another germanium diode. However if the only concern is to get a lower forward voltage drop than that of a silicon diode (0.7V), then a schottky barrier diode may be a suitable replacement as its forward voltage drop (<0.1V) is even lower than that of a germanium diode (0.2V).
Is 1N4007 OA79 silicon or germanium diode?
The entire 1N40xx series of power diodes are all silicon. The OA79 small signal diode is germanium.
What is the cutting voltage of a silicon diode?
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.
What is material made of a zener diode?
SILICON same as any other diode but with different characteristics
Why silicon crystal are suitable for making a diode and have a junction of P-type and N-type material?
you can find silicon and germanium materials has 4 valence electrons. This makes them to be useful to make p type and n type materials easily.They are very cheap compare to others.

What parameter in a germanium diode differs from those in a silicon diode?
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.

What is the definition of silicon diode?
A silicon diode is a tiny electronic component having two terminals, usually a switch or limiting device.
A silicon avalanche photo diode is fabricated by what process?
A silicon avalanche photo diode is fabricated by the process called impact ionization.
What is pn junction diode?
It's a rectifier diode made simply by combining P type and N type silicon. Where the two are joined, forms a junction that allows conduction in one direction only. A pn junction diode is a diode obtained by by dopping a silicon crystal through the process of covalent bond.
What will be the result if silicon diode is replaced by the germinium diode?
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.

What is the difference between a germanium diode and a silicon diode?
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)
