Question

why do impure silicon act as a semiconductor?​

Answer 1

Answer:Addition of impurity will change the conductor ability and it acts as a semiconductor. ... When an impurity is added to silicon or germanium without modifying the crystal structure, an N-type material is produced. In some atoms, electrons have five electrons in their valence band such as arsenic (As) and antimony (Sb).
