A: They both have redeemable quality. Germanium has lower turn on voltage as compared to silicon however their current capability is not too great and also have a problem leaking with temperature. SO THE USE IS DEPENDENT ON APPLICATIONS

Which type of diode having knee voltage of 0.7V to 0.3V?
Silicon = 0.7v : Germanium = 0.3v
When a diode is properly forward biased what is the voltage drop across it equal to?
The forward biased voltage drop of a diode depends on the type of diode and the current through the diode. A typical silicon diode will exhibit a voltage drop between 0.6v and 1.4v depending on current. An LED might range from 2v to 3v. A germanium diode might go a low as 0.2v. Bottom line; it varies.
What are the amount of voltage across the diode?
The amount of (forward biased) voltage across a diode is dependent on current and temperature. A typical silicon diode has a forward voltage of about 0.6V at low current and temperature. As current goes up, voltage goes up slightly, with a typical voltage being 1.4V at high current. As temperature goes up, voltage goes down slightly, but the maximum current rating also goes down.
What type of diode is used to convert alternating current into direct current?
The type of diode used to convert alternating current in to direct current is the power diode.
When silicon is doped with phosphorous what type of semiconductor results?
it would be a n-type semiconductor because phosphorus has more valence electrons than silicon does.
Which type of diode having knee voltage of 0.7V to 0.3V?
Silicon = 0.7v : Germanium = 0.3v
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.
Why silicon is the more semiconductor than germanium?
Silicon is more semiconductor than Germanium because the characteristics of silicon can be easily modified to obtain either a p-type or n-type material.
Why we can't use silicon and germanium in laser diode?
becoz Si and Ge are indirect bandgap semiconductors. for lasing action direct bandgap semiconductors are required of the type In Ga As P
What type of material is a transitor made from?
germanium or silicon crystal

How does the cut in voltage effects the output of a diode?
The cut in voltage is that voltage where after the current increase rapidly and it's value is different-2 for different type of semiconductor. for silicon it is 0.7 and for germanium it is 0.3 volt. It means if you made a diode from silicon than applied voltage below 0.7 volt will not able to flow current (if flow than it is in term of few micro ampere) . it means diode will stay in off mode and for germanium same things will happen and it will rest on off condition below 0.3 volt(applied).
What is led and how does it work?
A light emitting diode is a special type of diode made of transparent semiconductor (silicon & germanium are opaque) like aluminum indium gallium phosphide. The selected semiconductor must also have a large enough band gap that when electrons fall into holes photons are emitted.
What is a type of metalloid?
Examples: germanium, selenium, tellurium, antimony, boron, silicon.
Can IInd group elements be used with silicon to make P- type semiconductor?
germanium
What type of bond is present in germanium?
Germanium atoms are hold together through covalent bonds, although they have more metallic character than carbon and silicon.
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.
