摘要：

Current instability and chaos induced during low-temperature avalanche breakdown in n-GaAs have been investigated at 4.2 K under longitudinal magnetic field. By increasing the longitudinal magnetic field intensity (3.5˜28 mT), the hysteresis width of the S-shaped I-V curve formed by the avalanche breakdown of neutral shallow donors showed appreciable narrowing and disappeared critically at 28 mT. With the further increase of the magnetic field intensity (28 ˜ 140 mT), a new unstable phase appeared in the I-V characteristics, followed by the spontaneous current oscillation including chaos. Effects of the transverse magnetic field have also been described. © 1990, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
