Which of the following will produce p-type semiconductor?
A. Silicon doped with phosphonus
B. Germanium doped with arsenic
C. Gallium doped with anenic
D. Germanium doped with gallium
A. Silicon doped with phosphonus
B. Germanium doped with arsenic
C. Gallium doped with anenic
D. Germanium doped with gallium
Correct Answer – 4
Germanium is group 14 element while gallium is group 13 element
Hence, ahole will be created, i.e., it will bep-type semiconductor.
