| Student Manual |  This experiment introduces students to the Hall Effect which is a fundamental principle of magnetic field sensing. Students will measure Hall coefficient and carrier charge concentration in a given semiconductor crystal which will help them to understand important concepts in semiconductor physics. In this experiment students will also learn the relationship between current and magnetic field in an electromagnet as well as in a semiconductor material. |
