Question

The resistivity of a semiconductor is approximately:

Options

• \[\sim 10^{18}\ \Omega\text{m}\]

• \[\sim 10^{-5}\text{--}10^{6}\ \Omega\text{m}\]

• \[\sim 10^{10}\text{--}10^{16}\ \Omega\text{m}\]

• \[\sim 10^{-8}\ \Omega\text{m}\]

Answer 1

Semiconductors have moderate resistivity, in the range \[10^{-5}\text{--}10^{6}\ \Omega\text{m}\], which is intermediate between conductors (\[\sim 10^{-8}\ \Omega\text{m}\]) and insulators (\[\sim 10^{10}\text{--}10^{16}\ \Omega\text{m}\]).
