Investigation of the production and technical use of InSb single crystals periodically doped by means of the Peltier effect

The production of periodically doped InSb crystals by Peltier effect modulation was studied for the Czochralski process. Some experimental observations, which characterize the modulation of the segregation constant, are discussed qualitatively An examination of the crystals by helicon diagnostics shows no influence on the wave propagation process by the periodic structure. Therefore the change in notation produced by Peltier effect is too small to be used for amplification or generation of microwaves.
