How will differentiate silicon and germanium diode from a group of diodes?
Simple, Use the multi-meter , switch to the diode option then connect the positive wire to the positive of diode n negative to the negative ( +ve wire red, -ve wire black) if the there is a reading of =~0.7V then it is silicon. and if it is =~ 0.3V then it is germanium.
Advantages of silicon over germanium?
silicon has a wider bandgap than germenium .silicon jeakage current small, easily available then Ga and break down voltage is more. knee voltage of si is 0.7and Ga is having 0.3then Si is very useful.
What does germanium do?
Germanium does no "do" anything.
Is germanium a conductor or an insulator?
neither, germanium is a semiconductor
What is basic material for making a transistor?
It is the middle portion of the transistor
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.
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 parameter in a germanium diode differs from those in a silicon diode?
A germanium diode has a lower forward voltage drop compared to a silicon diode, typically around 0.3V for germanium and 0.7V for silicon. Germanium diodes also have a higher reverse current leakage compared to silicon diodes.
Why germanium has larger leakage current than silicon?
Germanium has a smaller bandgap compared to silicon, leading to higher intrinsic carrier concentration and hence greater leakage current. Additionally, germanium has a higher intrinsic carrier mobility, which can further contribute to increased leakage current compared to silicon.
Why is germanium more metallic than silicon?
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 Maximum spectral response of the germanium and silicon is in the?
The maximum spectral response of germanium is in the infrared region, while the maximum spectral response of silicon is in the visible light region. Germanium has a broader spectral response range compared to silicon.
Why the breakdown voltage of silicon is 0.7V whereas for germanium it is 0.3V?
The difference in breakdown voltage between silicon (0.7V) and germanium (0.3V) is mainly due to their different band gap energies. Silicon has a larger band gap compared to germanium, resulting in a higher breakdown voltage. This means that silicon can withstand a higher voltage before breaking down compared to germanium.
Why depletion region is small in germanium compared to silicon?
The depletion region is smaller in germanium compared to silicon because germanium has a lower bandgap energy, meaning that charge carriers can easily cross the depletion region and recombine on the other side. This results in a smaller built-in potential and a smaller depletion region in germanium.
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 germanium is better than silicon?
products made by silicon are more stable than those made by germanium
Why don't use germanium in silicon controlled rectifier?
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)
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.
