When a sample of germanium and silicon having same impurity density are kept at room temperature then resistivity of both?
Resistivity of silicon higher than that of germanium
What is the effect of adding impurity on viscosty of liquid?
This depends on the type of this impurity.
What are the main impurity in iron ore?
Sand (Silicon dioxide) and carbon. Other impurities are sulphur and phosphorus compounds. The silicon dioxide , sand, is removed in the blast furnace, and makes 'salg', calcium silicate. The other impurities are removed in the BOS plant, where an oxygen lance, removes the sulphur and phosphorus compounds and carbon percentage is adjusted.
Which is the pentavalent impurity is boron or germanium or indium or antimony?
Which is the pentavalent impurity is boron or germanium or indium or antimony
How does the melting behavior of lauric acid would change if an impurity was introduced in the sample?
An impurity lowers the melting point.
Which serve as a donor impurity in silicon?
Which will serve as a donor impurity in silicon is boron or germanium or antimony or indium
What element is the donor impurity in silicon?
Silicon has 4 valence electrons. When a penta-valent impurity like phosphorus is added, conduction takes place through the excess electron, the donor. Arsenic is another good example of a donor impurity
Which of the following elements would be suitable as a donor impurity in an n-type silicon semiconductor a. B b. Ga c. C d. As e. Ge?
e. Germaniumm
Why trivalent impurity is used?
Trivalent impurity is used to create a free electron when bonded with a silicon crystal.
What happens when you add a small amount of impurity to silicon it turns into a?
semiconductor.
What is p type silicon substrate?
Wafers are formed of highly pure defect-free single crystalline material. Donor impurity atoms, can be added to the molten intrinsic material changing it into n-type or p-type extrinsic semiconductor.
Does silicon dioxide contain carbon?
Silicon dioxide contains only silicon and oxygen - no carbon., The only carbon in a sample labelled " silicon dioxide", would be an impurity or contaminant probably on the surface
When a sample of germanium and silicon having same impurity density are kept at room temperature then resistivity of both?
Resistivity of silicon higher than that of germanium
What are the impuritys in pig iron?
The main impurities in pig are carbon (C) and Silicon (Si)
What is meant by step graded junction?
A step graded junction is the pn junction in which impurity concentration does not change abruptly from donor to acceptor but varies smoothly
Is gallium used in computers?
Yes. Gallium is used as a "dopant", a calculated impurity that turns the silicon that makes up the computer chip from a nonconductor to a semiconductor.
Is coffee an impurity?
if dissolved in water, it can be called an impurity.
