The electrical properties of the silicon change with the change of the temperature.
The semiconductor is used in the electronic circuit.
Semiconductors are widely used in electronic chip because of its variable electrical properties.
So, let's study the Introduction to semiconductor
We have studied that metals are good conductors of electricity and insulators are a poor conductor of electricity.
And the Semiconductors are those materials/elements whose electrical properties lie in between the metal and the insulators.
Silicon (Si) is the most common example of the semiconductor.
It is observed that the electrical properties of the semiconductor changes with the change of temperature.
Therefore at 0K the semiconductor behaves as an insulator and at higher temperatures it conducts electricity.
Now, the semiconductors are categorized as single semiconductors and compound semiconductors.
The naturally occurring elements found in the periodic table and showing the properties of the semiconductor are called single elemnt semiconductor.
Examples of single element semiconductor are,
And certain chemical compounds that behave as a semiconductor are called as a compound semiconductor.
The examples of the Compound semiconductor are,
Again there are two types of the semiconductor on the basis of purity of semiconductor.
That semiconductor which is made by only one element is called intrinsic semiconductor.
The examples of the pure or intrinsic semiconductor are,
Further, the extrinsic type semiconductor is called as doped semiconductor because some extra impurities are added to enhance the electrical properties.
So in the extrinsic semeiconductor, the electrical property of the element can be changed as per our needs.
The semiconductor can be used as an electrical sensor because of variable electrical properties.
We have learned the electric properties of the semiconductor.
