Engineering English
P-n Junction
Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: The boundary or interface between p-type and n-type semiconductor materials. It is the fundamental building block of diodes, transistors, and many other semiconductor devices.
Example in context
“The depletion region width at a p-n junction under reverse bias determines the device breakdown voltage.”
“Ters kutuplama altındaki bir p-n eklemindeki tükenme bölgesi genişliği, cihazın kırılma voltajını belirler.”
Where engineers use it
Engineers use p-n junction analysis when designing diode rectifiers, transistor amplifiers, and solar cells. Understanding its current-voltage characteristics is critical for circuit simulation and device optimization.
Synonyms: junction, diode junction
Antonyms: metal-semiconductor junction
Practice: can you use “P-n Junction” at work?
A junior engineer is debugging a power supply circuit where the rectifier diode shows unusually low forward voltage drop. Ask them to measure and explain the p-n junction properties.
Show a model answer
“Explain how the p-n junction behaves under forward and reverse bias conditions.”
