Question

What is the conductivity of a semiconductor sale having electron concentration of $5 \times {10^{18}}\,\,{m^{ - 3}},$ hole concentration of $5 \times {10^{19}}\,\,{m^{ - 3}},$ electron mobility of 2.0 m² V^$-$1 s^-1 and hole mobility of 0.01 m² V^$-$1 s^$-$1 ?

(Take charge of electronas 1.6 $ \times $ 10^$-$19 c)

1.68 ($\Omega $-m)^$-$1

1.83 ($\Omega $-m)^$-$1

0.59 ($\Omega $-m)^$-$1

1.20 ($\Omega $-m)^$-$1
