Built using combinations of diodes and transistors to perform logical operations (AND, OR, NOT) in computers. 7. Conclusion
Formed by adding pentavalent impurities (e.g., Phosphorus, Arsenic). These have 5 valence electrons, leaving one free electron to conduct electricity. Electrons are the majority carriers.

A wall of text is boring. Your file should include:
When a p-type semiconductor is joined with an n-type semiconductor, a junction is formed. At this junction, electrons from the n-side diffuse to the p-side and recombine with holes. This creates a region devoid of free charge carriers called the . An electric field is set up, creating a Potential Barrier (approximately 0.7V for Silicon).
