Doping In Semiconductors
Concepts to remember on Doping in Semiconductors:
-
Doping:
Mnemonic: “Dipping" - Add a little impurity to change properties
-
Donor atoms:
Mnemonic: “Donate some electrons like a kind giver"
-
Acceptor atoms:
Mnemonic: “Accept some electrons like a helping friend"
-
N-type semiconductors:
Mnemonic: “Naughty Electrons take charge”
-
P-type semiconductors:
Mnemonic: “Positive for Holes”
-
Extrinsic semiconductors:
Mnemonic: “Extra Dopants Take Over"
-
Majority carriers:
Mnemonic: “Majority calls the shot!"
-
Minority carriers:
Mnemonic: “Minority has a minor role in the game"
-
Doping concentration:
Mnemonic: “Concentration of the impurity gang"
-
Band gap:
Mnemonic: “Gap between valence and conduction avenues”
-
Fermi level:
Mnemonic: “Middle ground where 50% electrons reside"
-
Depletion region:
Mnemonic: “Vacant area, depleted of charges"
-
Built-in potential:
Mnemonic: “Nature’s inherent electrical difference"
