Abstract:

The background of thermal carriers is included in a theory for helical instabilities in electronhole plasmas. The theory applies to any injection level in intrinsic, n-type, and p-type semiconductors and to insulators. Given the temperature dependence of the mobilities, one can determine the plasma temperature from the electric field at the onset of instability. The n the frequency of the instability can be calculated. A comparison with Ancker-Johnsons experiment in p-InSb shows that the calculated frequencies are within 20 of the experimental values for high magnetic fields, and are a factor circa 2 smaller for low fields. The calculated plasma temperature reaches the optical phonon energy at an electric field of approximately 55 VCM, AND REMAINS CLOSE TO THIS TEMPERATURE FOR HIGHER FIELDS. The results of numerical calculations for a number of different materials are given. Author
