This paper represents the second part of Handel's PhD thesis on instabilities, turbulence and flicker-noise in semiconductors, focusing on current instabilities induced by their own magnetic field. The research extends the instability analysis by including self-generated magnetic field effects from high current densities in semiconductors, showing how current flow creates magnetic fields that couple back to modify carrier dynamics and produce additional instability mechanisms contributing to 1/f noise and turbulent behavior in semiconductor devices.
