Answer Posted / m.kamarajan
Drift Current
Due to thermal generation electron-hole moves but cannot
constitute of any current.when the voltage is applied
across the P-N Junction electron as well as hole motions
occurs,due to this current flows through the P-N
Junction,this current is called as drift current
Diffusion Current
If doping is non uniform, charge carriers in high
concentration area moves to low concentration area to
achive uniform concentration,this process is called
difussion process.Due to diffusion process the electrons
moves from n side to p side and holes moves fron p side to
n side,due to this movement current flows through the P-N
junction, this current is called as diffusion current.
