A pure Si crystal having \(5 \times 10^{28}\) atoms \({m}^{-3}\) is dopped with 1 ppm concentration of antimony. If the concentration of holes in the doped crystal is found to be \(4.5 \times 10^{9} {~m}^{-3}\) , the concentration (in \({m}^{-3}\) ) of intrinsic charge carriers in Si crystal is about
- \(1.2 \times 10^{15}\)
- \(1.5 \times 10^{16}\)
- \(3.0 \times 10^{15}\)
- \(2.0 \times 10^{16}\)
Answer
(B) 1.5 10^ 16
