ABSTRACT:
An anomalous intensification of the infrared emission from n-InSb having a central wavelength almost equal to the energy gap has been observed, as a result of the cooperation of the magnetoconcentration effect and the photo-excitation, in the temperature range from 80.degree. to 300.degree. K. This suggests that a light amplifier which operates at room temperature can be realized through the process for photons with a wavelength corresponding to the energy gap of the semiconductor material forming the light amplifier concerned. Also the cooperation of the magneto-concentration with the photo-excitation has another useful application as a tunable light source controlled by varying the applied magnetic field through the interband Landau-level transitions at liquid helium temperatures.
