At a certain temperature in an intrinsic semiconductor, the electrons and holes concentration is 1.5 \(\times\) 1016 m-3. When it is doped with a trivalent dopant, hole concentration increases to 4.5 \(\times\) 1022 m-3. In the doped semiconductor, the concentration of electrons (ne) will be:
- 3 \(\times\) 106 m-3
- 5 \(\times\) 107 m-3
- 6.75 \(\times\) 1038 m-3
- 5 \(\times\) 109 m-3
Answer
(D) 5 10 9 m -3
