• 論文の詳細を見る

• Well above the threshold for acoustoelectric instability, the time-dependent Ginzburg-Landau equation governing the motion of a phonon system in the threshold region breaks down on account of the parametric generation of subharmonic phonons, and in some cases it gives rise to an undamped oscillatory behavior of the system. It is suggested that the tremendous fluctuation in the acoustoelectric current is a manifestation to this behavior.
