Learn about 10 Difference between N type and P type semiconductor

Welcome to the world of semiconductors! In this article, we’ll uncover the 10 Difference between N type and P type semiconductor. No complicated jargon, just straightforward explanations to help you understand the distinctions between these materials. Let’s get started!

10 Difference between N type and P type semiconductor

Doping: N-type semiconductors are doped with impurities to add excess electrons, while P-type semiconductors are doped to create vacancies called holes in the electron structure.

Majority Carriers: N-type semiconductors have excess electrons as majority carriers, while P-type semiconductors have holes as majority carriers.

Minority Carriers: N-type semiconductors have holes as minority carriers, while P-type semiconductors have electrons as minority carriers.

Conduction Mechanism: N-type semiconductors conduct electricity through free electrons, while P-type semiconductors conduct through holes.

Electron Flow: In N-type semiconductors, electrons flow from the negative terminal to the positive terminal, while in P-type semiconductors, holes flow from the positive terminal to the negative terminal.

Charge Carriers: N-type semiconductors have a negative charge overall due to excess electrons, while P-type semiconductors have a positive charge overall due to excess holes.

Impurity Elements: N-type semiconductors are doped with impurities like phosphorus or arsenic, while P-type semiconductors are doped with impurities like boron or gallium.

Energy Band Diagram: In N-type semiconductors, the valence band and conduction band overlap, allowing electrons to move freely. In P-type semiconductors, there is a small energy gap between the valence band and conduction band, creating a barrier for electron movement.

Hall Effect: N-type semiconductors exhibit a negative Hall effect, where voltage is generated perpendicular to the current and magnetic field. P-type semiconductors exhibit a positive Hall effect, with voltage generated in the opposite direction.

Applications: N-type semiconductors are used in devices like transistors, solar cells, and LEDs. P-type semiconductors are used in complementary electronic components like P-N junction diodes and CMOS circuits.
