The conductivity of intrinsic semiconductors, such as silicon and germanium, can be increased when small amounts of group 3A or group 5A elements are added, a process called doping. The resulting semiconductors are called either p-type or n-type semiconductors. Classify the type of doping condition and diagrams depicting the electron population of molecular orbital energy-level bands as p-type or n-type semiconductors.
