Best Answer

In semiconductor uses, such as diodes and transistors, the forward voltage drop for Silicon (Si) is a little less than 0.7 volts, while the FVD for Germanium (Ge) is about 0.3 volts.

What is the cut in voltage of germanium and silicon diodes?

cut in voltage *** for silicon is 0.7volts and that for germanium is 0.3volts.According to Millman and Taub, "Pulse, Digital and Switching Waveforms", McGraw-Hill 1965, the cutin (or offset, break-point or threshold) voltage for a silicon diode is 0.6, and 0.2 for germanium.Breakdown voltage is another thing entirely. It is the reverse voltage at which the junction will break down.


Why Silicon transistor are preferred to germanium transistors?

)silicon has got less leakage current 2)high threshold voltage (to avoid unwanted triggering of the device from noise) 3)more adhesive to aluminum


What is the difference of silicon diode and germanium diode?

A silicon diode has a voltage drop of approximately 0.7V, while a germanium diode has a voltage drop of approximately 0.3V. Though germanium diodes are better in the area of forward voltage drop, silicon diodes are cheaper to produce and have higher breakdown voltages and current capabilities.


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 is preferred over other materials in designing ic?

because1) knee voltage of silicon is .7V where as germanium has .3V 2)silicon breakdown take place at around 200 0C and germanium at 90 0C


Why the breakdown voltage of silicon is 0.7V whereas for germanium it is 0.3V?

because germanium has lower energy gap between conduction and valence bands


Which type of diode having knee voltage of 0.7V to 0.3V?

Silicon = 0.7v : Germanium = 0.3v


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.


Why cut in voltage of silicon is more than that of germanium?

the valence band energy is different in the two substances,so the cut in voltage is different.


What is the typical threshold voltage ranges for silicon gate p-channel IGFET?

2-3v


Where is germanium and silicon located in computer chips?

Germanium is not used in integrated circuits. Silicon is.


Can you give examples of elements that are metalloids?

The metalloids are Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium.
