In semiconductors, the range of conductivity will be

The conductivity range of semiconductors ${10}^{-6} \mathrm{to} {10}^4{\mathrm{ohm}}^{-1}{\mathrm{m}}^{-1}$ conductors ${10}^4-{10}^7 {\mathrm{ohm}}^{-1 }{\mathrm{m}}^{-1}$,Insulators      ${10}^{-20} {\mathrm{ohm}}^{-1} {\mathrm{m}}^{-1}-{10}^{-10} {\mathrm{ohm}}^{-1} {\mathrm{m}}^{-1}$.
