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
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)
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
If it's a germanium transistor, 0.3 volts. If it's the more common silicon transistor, slightly more than 0.6 volts.
silicon diodes Cut in voltage is 0.7 V.but the Germanium cut in voltage is 0.3 V that's why .............
silicon has several properties that make it preferable to germanium, the main ones being:higher junction temperature of operation without damage, 150C vs. only 60Csilicon dioxide is a stable insulator making passivation, inexpensive plastic packages, and monolithic ICs possible vs. germanium oxide is a powdery water soluble solid requiring expensive hermetically sealed metal or glass packagessilicon is more abundant than germanium on the earth
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.
products made by silicon are more stable than those made by germanium
Silicon is more abundant than germanium and can operate at higher temperatures, making it more suitable for a wider range of applications. Additionally, silicon has a higher bandgap energy, which results in lower leakage currents and allows for greater integration density in electronic devices.
Germanium has a smaller band gap compared to silicon, allowing it to conduct electricity more effectively. Its crystal structure also has a closer packing arrangement of atoms compared to silicon, making it more metallic in nature. Overall, these factors contribute to germanium exhibiting more metallic properties than silicon.
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.
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.
Silicon has a higher operating temperature and better thermal stability compared to germanium, making it more reliable for electronic devices. Additionally, silicon's oxide layer forms a better insulating material for integrated circuits, enhancing its performance. Silicon also has a wider bandgap than germanium, allowing for better control of electrical conduction.
Silicon is a more popular semiconductor than germanium due to factors such as its wider band gap, higher thermal stability, and better abundance in nature. Silicon also has better manufacturing processes and can operate at higher temperatures, making it more suitable for a wide range of electronic applications.
Silicon has 14. Germanium has 32. You figure it out.
Silicon has a larger band gap energy than germanium, resulting in a higher cut-in voltage for silicon diodes compared to germanium diodes. The larger band gap in silicon means that it requires more energy for electrons to be excited into the conduction band, resulting in a higher cut-in voltage.
because lekage current of silicon is less than germenium
One element that is semiconducter is Silicon. 2nd answer: One common element used to manufacture a semiconductor is silicon. Germanium has also been widely used, and is more sensitive to tiny voltage changes than silicon. The compound gallium arsenide is very common in the manufacture of semiconductor material, as well.
