Discussion session questions: Circle the correct answer: Silicon and germanium are examples of semiconductors with the (perovskite / diamond cubic / zinc blende) crystal structure. In silicon, each Si atom is covalently bonded to (3 Si atoms / 4 Si atoms / 5 Si atoms) InSb and GaAs are examples of semiconductors with the (perovskite / diamond cubic / zinc blende) crystal structure. In GaAs, each Ga atom is bonded to (3 Ga atoms / 4 As atoms / 5 Ga atoms / none of the above). Dopants are intentional impurities which are added to control the conductivity of the semiconductor to a desired level. In silicon and germanium, if we desire a p -type semiconductor, we choose to add an element from (group III / group IV / group V) of the periodic table. The majority carrier is a (hole / electron). If instead we desire an n -type semiconductor, we choose to add an element from (group III / group IV / group V) of the periodic table. The majority carrier is a (hole / electron). In GaAs, if we desire a
