Detailed Solution

Concept: The term "semiconductor" refers to a substance that can conduct a little quantity of electricity. The two main categories of semiconductors are. Both intrinsic and extrinsic semiconductors describe them. N-type and p-type semiconductors are subcategories of extrinsic semiconductors.
Semiconductors have conductivities that fall in between those of conductors and insulators. The term "semiconductor" refers to a substance that can conduct a little quantity of electricity.
The manner in which semiconductors operate.
The majority of semiconductors are created using silicon since it is widely available on the planet and simple to work with during manufacturing. When modest amounts of contaminants like boron or gallium are added to silicon, the stable silicon crystal becomes unstable. This instability releases the electrons from their confinement. Due to the creation of free electrons, there is an imbalance in the electron population. The imbalance of electrons causes the generation of a charge. It is possible for this charge to be positive or negative. If there are fewer electrons than holes, the charge will be positive. If there are more electrons than holes, the charge will be negative. Semiconductors are divided into p-type and n-type semiconductors based on the polarity of the charge produced. P-type semiconductors are defined as those that produce a positive charge. The term "n-type semiconductor" refers to semiconductors that produce a net negative charge.When the impurities are combined with the silicon, the semiconductors produce a charge.
Hence, option 1 is the correct answer.
