Jean's instability in a drifting dusty plasma in the presence of secondary electron emission

Abstract

In this paper, we have studied the effect of dust drift on Jean's instability in a complex plasma in the presence of secondary electron emission from dust grains. The drift motion of dust grains is shown to be responsible for the excitation of dust-ion-acoustic Jean's mode (DIAJ), which grows with oscillation at a frequency depending exclusively on the dust drift. This oscillation of the growing DIAJ mode develops due to energy loss of the wave to the dust grains and the ions when the drift velocity is nearly equal to the phase velocity of the wave.
