Vedclass · Answer

(B) When a strong current passes through a semiconductor,it generates heat within the crystal lattice. This thermal energy causes the covalent bonds to break,leading to the generation of a large number of free electrons and holes. This sudden excess of charge carriers leads to a thermal runaway effect,which damages the semiconductor material.
