Answer Posted / karanrathod
In semiconductor electron vibration happen at room
temperature. But at very low temperature electron can not
get energy and so it can not vibrate. and so current can not
pass,so semiconductor act as an insulator. And when
temperature increasing electron get vibration and so more
current passed so conductivity is increases
