Dynamic chaos in acoustoelectronic systems

Technical Physics Letters, 1997
The experimental observation and study of dynamic chaos in acoustoelectronic systems is reported. For these investigations we selected an object, well-known in physical acoustics and acoustoelectronics, in which these new nonlinear properties are observed.

Theory of acoustoelectronic effects in low-dimensional conductors

Czechoslovak Journal of Physics, 1996
Basing on the assumption of effectively reduced dimensionality of electron gas in layered and chained conducting crystals, we predict some peculiarities in ultrasound—charge carriers interaction at low temperatures.

Acoustoelectronic Rayleigh Wave Devices

1985
Electrons or charged particles can be made to interact with the electric fields of Rayleigh waves in piezoelectric crystal surfaces. The charged particles can be in vacuum, in semiconductors or bound to traps in solids or on surfaces. During the past two decades a large variety of acoustoelectronic amplifiers, signal processors and image processing ...

Nonlinear acoustoelectronic interaction in thin superconducting lead films

Physics of the Solid State, 1997
The effect of high-power surface acoustic waves (SAW) on the superconducting state of Pb films has been studied in different transverse magnetic fields. It was established that a high-intensity sound wave affects the T c of the film and the character of the superconducting transition, and that the observed changes are the larger, the higher is the SAW ...

Acoustoelectronic Interaction in InGaAsP∕InP Laser Heterostructures

Physics of the Solid State, 2005
The dynamics of change in the spectral characteristics of the emission from a laser heterostructure due to an alternating strain induced by a surface acoustic wave is investigated. The spectral distributions of the laser radiation intensities are analyzed with the aim of elucidating the mechanisms responsible for the interactions occurring in the laser
