Variation of conductivity of an intrinsic semiconductor with temperature and it's explanation
\[1 / 2+1 / 2
\] Graph showing variation of conductivity with temperature
\[\] Conductivity will increase. As the temperature increase , more thermal energy becomes available to these electrons and some of these electrons may break -away ( becoming free electrons contributing to conduction)
