Why is it Called P-Type? | Semiconductor Quick Revision 🔬 #shorts #examprep #physics #semiconductors

The "P" in P-type doesn't stand for positive charge, but for Positive charge carriers (Holes)! Here’s a rapid revision on how they are manufactured.

Process Explained:

1. Start with Pure (Intrinsic) Semiconductor.
2. Dope it with a Trivalent Impurity (Group 13 element).
3. Each dopant atom creates a "Hole" or Acceptor Level.
4. Holes become the Majority Charge Carriers.
