In an extrinsic semiconductor, the number density of holes is 4 \(\times\) 1020 m-3. If the number density of intrinsic carriers is 1.2 \(\times\) 1015 m-3, the number density of electrons in it is
- 1.8 \(\times\) 109 m-3
- 2.4 \(\times\) 1010 m-3
- 3.6 \(\times\) 109 m-3
- 3.2 \(\times\) 1010 m-3
Answer
(C) 3.6 10 9 m -3
