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 else can I help you with?
Can you give examples of elements that are metalloids?
The metalloids are Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium.
Why the temperature sensitivity of silicon is less than germanium?
The temperature sensitivity of silicon is less than germanium because silicon has a wider energy band gap than germanium. This wider band gap allows silicon to operate more efficiently at higher temperatures, resulting in less temperature-dependent changes in its electrical properties compared to germanium. Additionally, silicon has a higher thermal conductivity than germanium, which helps dissipate heat more effectively, reducing temperature effects on its performance.
Why leakage current of germanium is more than silicon?
The higher leakage current in germanium compared to silicon is mainly due to its lower bandgap energy, which allows more thermally generated carriers to flow through at room temperature. Additionally, germanium has lower electron mobility and higher intrinsic carrier concentration than silicon, contributing to increased leakage current.

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)
Why germanium and silicon are considered as best semiconductors?
actually diamond should be much better, if fabrication issues can be solved, it is faster and will operate up to 600ºC junction temperature. Silicon is limited to 150ºC junction temperature and Germanium is limited to 50ºC to 60ºC. Germanium was originally used because it was easiest to purify and process. Silicon is the cheapest material now, it comes from sand and there is no shortage of that.
Why germanium and silicon are not preferred in LEDs?
A: Because the element has different property as gallium arsenide.
Why don't we use germanium as a control device in silicon control rectifier?
Generally SCR is used at high power applications, in order to withstand the temperature dissipated in the SCR, THERMAL STABILITY is very high enough. It means that thermal stability of silicon is very high compared to germanium that's why germanium is not preferred. But that does not mean it is not possible, in fact before silicon became common in the 1960s devices equivalent to the SCR were built using germanium!
Why germanium is not used in fabrication of thyristor?
Germanium is not commonly used in the fabrication of thyristors primarily due to its lower thermal stability and higher leakage current compared to silicon. Silicon's superior electrical properties, including a wider bandgap and better temperature handling, make it more suitable for high-power applications. Additionally, silicon's well-established manufacturing processes and availability further enhance its preference over germanium in thyristor production. As a result, silicon-based thyristors are more reliable and efficient for modern electronic applications.
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 silicon is preferred over carbon in fabrication of semiconductor?
Silicon is preferred over carbon for semiconductor fabrication because it is abundant, easily obtained in high purity, and has well-established processing techniques. Silicon also has a higher mobility for charge carriers, making it more efficient for electronic applications compared to carbon. Additionally, silicon dioxide forms a stable insulating layer with silicon, enabling the creation of reliable semiconductor devices.
What is difference between silicon and germanium semiconductors?
Silicon has a higher operating temperature and greater thermal stability compared to germanium. Silicon has a larger bandgap energy which makes it better suited for high-power applications. Germanium has a higher electron mobility which can result in faster transistors, but it is less commonly used in modern semiconductor devices.
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.
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.
Where is germanium and silicon located in computer chips?
Germanium is not used in integrated circuits. Silicon is.
