Question

If the doping level of a crystal diode is increased, the width of depletion layer _____."

Answer 1

HIII MATE!!

The width of the depletion layer is inversely proportional to the concentration. Hence, the width will decrease when the doping is increased. 

THEREFORE, DECREASED IS THE ANSWER.

THANKS
I THINK IT HELPS...

Answer 2

If the doping level of a crystal diode is increased, the width of the depletion layer 'is increased'

• The more doping in semiconductors, the more conductive and less resistive it becomes
• Since the width of the depletion layer is inversely proportional to the doping concentration hence the width will decrease when the doping is increased.
• The crystal diode can be used as a rectifier to convert the AC into DC.
• As it conducts only in one direction and blocks the current flow in the reverse direction similar to the normal diode- it can be used to design the half wave, full wave, and bridge rectifier circuits.
