junction breakdown and tunnel diode 특징
The reverse-bias voltage may not increase without limit; at some particular voltage, the reverse-bias current will increase rapidly.
The applied voltage at this point is called the ‘breakdown voltage’.
1. Zener effect
2. Avalanche effect
Depletion layer controls reverse-bias current by doping impurities.
In case of high doping,
-> reverse-bias current increase.
In case of low doping,
-> reverse-bias current decrease
