WebJul 5, 2024 · The main points about band gaps: The band gap is the minimum amount of energy required for an electron to break free from its bound state and become conductive (flow freely in the material). When an electron becomes conductive, a hole is left behind. This hole flows in the opposite direction of the electron, and also participates in … WebDescription: The objective of this educational module is to measure the Hall effect germanium and determine the carrier concentration (and type) as a function of temperature. Germanium is an indirect bandgap semiconductor with a room temperature bandgap EG = 0.67 eV. As discussed in the module on Hall effect measurements
