Questions
A semiconductor is known to have an electron concentration of per cm³ and a hole concentration of per cm³. The semiconductor is
detailed solution
Correct option is A
Given that, Electron concentration ne=8×1013 per cm3 hole concentration nh=5×1012 per cm3ne>nhnumber of electrons > number of holes, so it is n - type semiconductor because majority charge carrier is electrons as its concentration is higher than hole.Similar Questions
