Quizplus · Accepted Answer

The diagram shows an n-type semiconductor, where an impurity atom (doped atom) with one extra electron is added to the semiconductor material. This impurity atom can donate its extra electron to the semiconductor crystal lattice, creating a mobile charge carrier (free electron). Therefore, the semiconductor is carrying an extra electron.
