How will differentiate silicon and germanium diode from a group of diodes?
Simple, Use the multi-meter , switch to the diode option then connect the positive wire to the positive of diode n negative to the negative ( +ve wire red, -ve wire black) if the there is a reading of =~0.7V then it is silicon. and if it is =~ 0.3V then it is germanium.
Advantages of silicon over germanium?
silicon has a wider bandgap than germenium .silicon jeakage current small, easily available then Ga and break down voltage is more. knee voltage of si is 0.7and Ga is having 0.3then Si is very useful.
What does germanium do?
Germanium does no "do" anything.
What is basic material for making a transistor?
It is the middle portion of the transistor
Is germanium a conductor or an insulator?
neither, germanium is a semiconductor
Why you prefer silicon atom as compared to germanium atom?

Can you explain why silicon and germanium are used in the manufacturing of semiconductors?
silicon is less sensitive towards temperature.It costs low compared to germanium,
Why leakage current of germanium is more than silicon?
Because the space charge region or depletion region is small in germanium compared to silicon hence leakage current is more in germanium than silicon
Why don't use germanium in silicon controlled rectifier?
the leakage current of silicon is less when compared with the leakage current of germanium.. hence scr's are made up of silicon than germanium.. hope tis one is useful to u all!- Vignesh.L(engineer, 1st year)
Why germanium is less used than silicon?
Germanium is costly, less abundant and there aren't as many feasible processes for it as compared to Si for fabrication.
Why is silicon more widely used than germanium?
because it can withstand more temperature compared to germanium and relatively cheaper and it is available abundantly in sand where as germanium is rare so Si has advantages than Ge though its conductivity is more compared to Si
Where is germanium and silicon located in computer chips?
Germanium is not used in integrated circuits. Silicon is.
Why is silicon is preferred is germanium?
Silicon is actually preferred to germanium within the manufacture of semiconductor devices due to the following reasons:Silicon is cheap and abundantIn silicon, leakage current is less affected by temperature as compared to germanium.The leakage current in silicon is very very small as compared to germanium.The working temperature of silicon is more than that of germanium. The working junction temperature of silicon can go as high as 150C whereas the working junction temperature of germanium can only go as high as 60CSilicon dioxide is a stable insoluble solid that can be used both to electrically insulate circuitry and to passivate junctions preventing contamination (allowing use of inexpensive plastic packages), germanium dioxide is a crumbly water soluble solid (this requires all germanium devices to be packaged in expensive metal or glass hermetically sealed cases and making germanium integrated circuits almost impossible)
Can you give examples of elements that are metalloids?
The metalloids are Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium.
What is more referred to use si diode or a ge diode?
silicon diode is preferred more when compared with germanium diode because in silicon diode the operating voltage is 0.7v where as in germanium diode the operating voltage is 0.3v , germanium is temperature sensitive so it can be easily destroyed by increasing temperature hence silicon diode is preferred more
Why silicon prefer to germiniuam?
Four reasons. First, it is a LOT cheaper and easier to get silicon. Germanium is a trace element in rocks. You need to mine and process lots of rock to get any germanium. Silicon is also known as sand--very easy to find. Second, germanium is heat sensitive. It's harder to solder a germanium device in than a silicon one because the heat can mess up the germanium. Germanium devices pretty much have to be soldered in by hand because you have to heat sink them, whereas silicon devices can be soldered in a soldering machine. Third, germanium's hazardous and silicon is generally not. People eat off glass plates, which are made from silicon. They do NOT eat from germanium plates, if they could even afford them. And fourth, germanium has a variable voltage drop--the higher the voltage, the greater the drop. If you pump 5000 volts into a silicon diode, you're going to get 4999.3v out the other side.
What element is used in making transistors and chips?
Silicon and Germanium are the elements used in transistors
