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 germanium is better than silicon?

products made by silicon are more stable than those made by germanium


Why is silicon a better semiconductor than germanium?

Silicon is a good semi conductor than germanium because silicon is more readily available, cheaper and stable.


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 is the reverse saturation current of germanium diode more than silicon?

Germanium has four number of shells while Silicon has three number of shell. therefore for germanium less energy is required to move the electron from valence band to conduction band if compared to silicon. So at room temperature for germanium their are more number of electrons present in conduction bond hence more number of holes present in the valence energy band. Due to movement of holes reverse saturation current is produced. Their is more number of hole movement in germanium comparatively therefore reverse saturation current is more than silicon for germanium.

Who has more protons neon or Silicon?

Silicon has 14. Germanium has 32. You figure it out.


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 has low leakage of current as compared to germanium?

Each has four valence electrons, but germanium will at a given temperature have more free electrons and a higher conductivity. Silicon is by far the more widely used semiconductor for electronics, partly because it can be used at much higher temperatures than 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 are some names of metalloids?

The six commonly recognized metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium.


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


Why silicon is preferred over germanium in the fabrication of p-n junction diode?

Germanium diodes are more expensive than silicon ones, germanium is harder to process, germanium cannot be used to make integrated circuits (while early prototype integrated circuits were germanium the wiring between the integrated components cannot be integrated making it too expensive for production), germanium cannot operate with a junction temperature above 60C (silicon will operate up to 150C), and its reverse leakage current is greater. However! Germanium diodes have a lower forward voltage drop than silicon ones do, so they're better for some applications, like radio frequency detection.
