摘要：
In the presence of a perpendicular weak magnetic field, current filaments in semiconductors can obtain a transverse drift. In the framework of a collective-coordinate ansatz, an expression for the velocity of the filament is derived for a simple type of extrinsic semiconductors. It turns out that the motion is caused by the coupling of the non-uniform Hall angle to the translational Goldstone mode of the current filament.
