Pinch Oscillations in Electron-Hole Plasmas

摘要

It is a well known fact that a strong current can produce pinching of nonequilibrium electron-hole plasmas in InSb; previous reports include a few observations of oscillations in the voltage. The report is a systematic treatment of both theory and observation of pinch oscillations in electron-hole plasmas. Part I contains the magnetothermal pinch theory, briefly proposed in 1964 by Drummond and Ancker-Johnson and here extended so that quantitative comparison with measurements can be made. The experimental measurements are presented and the results discussed in Part II. (Author)
