Which of the following is a Schottky barrier diode?
The correct answer is A: Metal-semiconductor junction. Which of the following is a Schottky barrier diode is a metal-semiconductor junction. Schottky diodes use metal-semiconductor junctions. For amateur radio operators, this is important for component knowledge. Understanding this helps when working with Schottky diodes.
Exam Tip
Schottky barrier diode = metal-semiconductor junction. Think 'S'chottky 'B'arrier = 'S'emiconductor-'B'oundary with metal. Schottky diodes use metal-semiconductor junctions. Not electrolytic, not PIN, not thermionic - just metal-semiconductor junction.
Memory Aid
"Schottky barrier diode = metal-semiconductor junction. Think 'S'chottky = 'M'etal-'S'emiconductor. Schottky diodes use metal-semiconductor junctions. Important for component knowledge."
Real-World Application
A Schottky barrier diode: It's a metal-semiconductor junction. Unlike regular diodes which use P-N junctions, Schottky diodes use a metal-semiconductor contact. This is what it is - metal-semiconductor junction.
Key Concepts
Why Other Options Are Wrong
Option B (Electrolytic rectifier): Incorrect. Electrolytic rectifier isn't a Schottky barrier - Schottky is metal-semiconductor junction. Electrolytic isn't Schottky.
Option C (PIN junction): Incorrect. PIN junction isn't a Schottky barrier - Schottky is metal-semiconductor junction. PIN isn't Schottky.
Option D (Thermionic emission diode): Incorrect. Thermionic emission diode isn't a Schottky barrier - Schottky is metal-semiconductor junction. Thermionic isn't Schottky.
