In a p-type semiconductor, germanium is doped with which of the following?(a) Gallium(b) Copper(c) Phosphorous(d) NitrogenI got this question during an interview.I need to ask this question from Extrinsic Semiconductor in portion Semiconductor Electronics : Materials, Devices and Simple Circuits of Physics – Class 12

Answer»

Right CHOICE is (a) Gallium

Best explanation: SUBSTANCES such as gallium, boron, and aluminum are all trivalent atoms. These are called acceptor impurities and they PRODUCE p-type semiconductors. Therefore, germanium is doped with gallium in a p-type semiconductor.
