What is the name given to an impurity atom that adds holes to a semiconductor crystal structure?
The correct answer is C: Acceptor impurity. What is the name given to an impurity atom that adds holes to a semiconductor crystal structure is acceptor impurity. Acceptor impurities create holes (P-type). For amateur radio operators, this is important for semiconductor knowledge. Understanding this helps when working with semiconductors.
Exam Tip
Impurity that adds holes = acceptor impurity. Think 'A'cceptor = 'A'dds 'H'oles (P-type). Acceptor impurities create holes (P-type). Not insulator, not N-type (electrons), not donor (electrons) - just acceptor.
Memory Aid
"Impurity that adds holes = acceptor impurity. Think 'A'cceptor = 'H'oles. Acceptor impurities create holes (P-type). Important for semiconductor knowledge."
Real-World Application
An impurity atom that adds holes to a semiconductor crystal structure: It's called an acceptor impurity. Acceptor impurities accept electrons, creating holes in the crystal structure. This is the name - acceptor impurity.
Key Concepts
Why Other Options Are Wrong
Option A (Insulator impurity): Incorrect. Insulator impurity isn't the name - acceptor impurity adds holes. Insulator impurity isn't the name.
Option B (N-type impurity): Incorrect. N-type impurity adds electrons, not holes - acceptor impurity adds holes. N-type impurity is wrong.
Option D (Donor impurity): Incorrect. Donor impurity adds electrons, not holes - acceptor impurity adds holes. Donor impurity is wrong.
