Physics Question on Semiconductor electronics: materials, devices and simple circuits
For a Zener diode
A
both p and n regions are heavily doped
B
p region is heavily doped but n region is lightly doped
C
n region is heavily doped but p region is lightly doped
D
both p and n regions are lightly doped
Answer
both p and n regions are heavily doped
Explanation
Solution
Both p and n are heavily doped, so that breakdown occurs easily.
