Surface acoustic waves in Ni/V superlattices.
%e have measured the surface-acoustic-wave velocities in Ni/V superlattices using both Brillouin scattering and surface-acoustic-wave techniques; the results are in good quantitative agreement. These results confirm earlier reports of phonon-velocity softening in bcc/fcc superlattices and prove that this is a general phenomenon, not a consequence of the measurement method. In addition, we descr...
متن کاملSuperheterodyne Detection of High Frequency Acoustic Waves
A laser ultrasonic system that allows for the excitation and detection of high frequency (GHz range) acoustic waves using low frequency, low cost detection electronics is presented. A continuous wave diode laser source, operating at a wavelength of 1544nm, is amplitude modulated using an integrated electro-absorption modulator and used to excite high frequency, narrow bandwidth acoustic waves. ...
متن کاملCurrent self-oscillations, spikes, and crossover between charge monopole and dipole waves in semiconductor superlattices
Self-sustained current oscillations in weakly coupled superlattices are studied by means of a self-consistent microscopic model of sequential tunneling, naturally including boundary conditions. Well-to-well hopping and recycling of charge monopole domain walls produce current spikes—high-frequency modulation— superimposed on the oscillation. For highly doped injecting contacts, the self-oscilla...
متن کاملDetermination of sediments diameter using acoustic waves
The use of acoustic waves in researches related to sea water is of most importance among scientists recently. Since these waves are the only waves, transmitted in water with lowest attenuation and high speed, they can be used in many scientific fields. The main goal of this research is to better understand the physics and mechanisms of sound-seabed interaction, including acoustic penetration, p...
متن کاملCapillary wave motion excited by high frequency surface acoustic waves
This paper presents a numerical and experimental study of capillary wave motion excited by high frequency surface acoustic waves SAWs . The objective of this study is to provide insight into the dynamic behavior of the fluid free surface and its dependence on the excitation amplitude. A two-dimensional numerical model that couples the motion of the piezoelectric substrate to a thin liquid layer...
