Gap Energy and Recombination Light in Germanium Movie Review 19??

An optical experiment visualizes the concept of the energy gap in semiconductors by measuring the wavelength of the light emitted by the recombination of excess hole-electron pairs in the neighborhood of a pn-junction. The intensity of the emitted radiation is also examined along the germanium bar and plotted as a function of the distance away from the junction.
