Question

An example of trivalent impurity is___​

Answer 1

An example of trivalent impurity is Aluminum.

Explanation:

• In the field of chemistry, trivalent impurities can be described as the impurities in which  the atom has three electrons in the outermost shell.

• These trivalent impurities are added to a semiconductor so that the conductivity of the semi conductor can be enhanced.

• The atomic number of aluminum is 13. Hence, its electronic configuration will be 2, 8, 3.

• Other trivalent impurities can include elements like Boron and Indium.
