Density and Mobility in N–Germanium/P–Germanium

P7213 586852
Solid-state physics – conduction phenomena.

  • Includes all major components
  • Includes two material options N and P type crystals
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.

Required but not included: PC with Windows XP/Vista/7/8/10 (x86 or x64).
