HELICAL INSTABILITIES IN SOLID-STATE PLASMA
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-Johnson's 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 V/CM, AND REMAINS CLOSE TO THIS TEMPERATURE FOR HIGHER FIELDS. The results of numerical calculations for a number of different materials are given. (Author)
