What else can I help you with?
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,
What is a good slogan for the element germanium?
Oh, dude, like, a good slogan for germanium could be "Germanium: It's like silicon's cool cousin." Because, you know, germanium is in the same family as silicon, but it's not as popular. So, it's like the hipster of the periodic table.
Why you use silicon not germanium in SCR?
because lekage current of silicon is less than germenium
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 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.

Why is silicon preferred over germanium?
Silicon is generally preferred over germanium for electronic applications because it has a higher bandgap energy, allowing for the creation of more efficient and faster electronic devices. Silicon is also more readily available and easier to work with in terms of manufacturing processes compared to germanium. Additionally, silicon has better thermal stability and higher breakdown voltage, making it more reliable for long-term applications.
Why you prefer silicon atom as compared to germanium atom?
Silicon is preferred over germanium because it is more abundant, less costly, and has a higher thermal stability. Silicon also forms a better oxide layer, making it more suitable for integrated circuit applications. Additionally, silicon has better electron mobility and is less susceptible to thermal runaway compared to germanium.
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)
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 transistor are preferred to germanium transistors?
Silicon transistors are preferred to germanium transistors because they exhibit higher thermal stability and are less prone to temperature variations. Silicon transistors also have a higher maximum operating temperature, improved frequency response, and are more reliable in terms of long-term performance. Additionally, silicon is more abundant and easier to work with in manufacturing processes compared to germanium.
Why is LED not made of silicon or germanium?
Silicon and Germanium are not used to make LEDs.They are opaque to visible lightThey have the wrong type of band gap (direct instead of indirect).LEDs are made with binary semiconductors, like:Indium Gallium NitrideSilicon CarbideIndium PhosphideGallium Indium Arsenide NitrideIndium Gallium Aluminum Phosphideetc.
Where is germanium and silicon located in computer chips?
Germanium is not used in integrated circuits. Silicon is.
What element is used in making transistors and chips?
Silicon and Germanium are the elements used in transistors
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.
What has more shells or rings germanium or silicon?
germanium
The modern name for eka-silicon?
germanium
Why silicon is preferred over other materials in designing ic?
Silicon is preferred in designing integrated circuits (ICs) because it is abundant, has good electrical properties, is easy to manufacture, and forms a stable oxide layer for insulation. These characteristics make silicon an ideal material for creating the transistors and other components used in ICs.
