Question

Which is better, silicon or germanium?

Answer 1

Silicon and germanium are used in semiconductor gadgets, the present-day pattern is to utilize silicon. At temperature, a silicon precious stone has less free electrons than a germanium gem. The variety of ICBO with temperature might be a more modest sum in silicon when contrasted with germanium.

Complete answer:
There are a few reasons Silicon has become the well-known semiconductor inside this, over Germanium. Simple arrangement of SiO 2 layer in silicon is better than germanium, during the assembling of cutting-edge electronic gadgets like MOSFETs, and so on. Silicon is really found in sand then, at that point it's the most reduced when contrasted with germanium.
Germanium is commonly found inside different mixtures due to its high reactivity. Silicon has a larger bandgap (1.12eV) than germanium (0.7eV). Along these lines, at a similar temperature, the warm pair age in silicon might be a more modest sum than germanium. Nonetheless, the germanium diode enjoys one significant upper hand over Si.
Ge has higher electron and opening portability and since of this Ge gadgets can work up to a much better recurrence than Si gadgets. The germanium diode is also better than silicon diode as far as energy misfortune, current misfortune, and so forth The Ge diode loses just 0.3-0.4 a volt while a silicon diode loses about 0.6-0.7 volts. Be that as it may, the value of creation and non-adaptability of germanium diodes makes it poorer than a silicon diode.

Note:
Silicon is regularly worked at a much better temperature when contrasted with germanium. The design of Germanium precious stones has the chance to be obliterated at higher temperatures. Additionally, Silicon includes a way more modest spillage current than that of germanium.
