Dependence of Hall Coefficient on Temperature (HEX-33C)
The set-up consists of the following. The Hall Probe comes complete with.
The Hall voltage for p-carriers has opposite sign from that for n-carriers. Therefore if a semiconductor with p-type doping is gradually heated up, more and more electrons from its valence band will go to conduction band. As a result hall voltage would fall rapidly with temperature and even become zero or change sign. At the point of zero Hall Coefficient, it is possible to determine the ratio of mobilities b=me/mh. The Hall coefficient inversion is a characteristic of only p-type semiconductors. The set-up consists of the following. The Hall Probe comes complete with 1.Hall Probe (Ge: p-type), HPP-33 Ge single crystal with four spring type pressure contacts is mounted on a glass-epoxy strip. Leads are provided for connections with the current source and Hall voltage measuring devices.
