Vedclass · Answer

(A) When the temperature of a semiconductor increases,the thermal energy causes more covalent bonds to break,leading to an increase in the number of free charge carriers (electrons and holes). This increase in charge carriers significantly increases the conductivity,which corresponds to a decrease in resistivity. However,the increased thermal vibrations of the lattice atoms lead to more frequent collisions,which causes the mobility of the charge carriers to decrease.
