Density and Mobility in N–Germanium/P–Germanium

Solid-state physics – conduction phenomena.

Explore the temperature-dependency of the Hall voltage and the electrical conductivity
using doped germanium samples. The concentrations of the charge carriers and their mobility's are determined under the assumption that, depending on the doping, one of the concentrations n or p can be ignored.
