Electronic configuration of germanium is 2, 8, 18 and 4. To make it extrinsic semiconductor small quantity of antimony is added [MP PET 1999]

• A. The material obtained will be N-type germanium in which electrons and holes are equal in number
• B. The material obtained will be P-type germanium
• C. The material obtained will be N-type germanium which has more electrons than holes at room temperature
• D. The material obtained will be N-type germanium which has less electrons than holes at room temperature
