Band gap of germanium with Cobra3
Principle: The conductivity of a germanium testpiece is measured as a function of temperature. The energy gap is determined from the measured values.
Tasks:
1. The current and voltage are to be measured across a germanium test-piece as a function of temperature.
2. From the measurements, the conductivity σ is to be calculated and plotted against the reciprocal of the temperature T. A linear plot is obtained, from whose slope the energy gap of germanium can be determined.
