Generation, Propagation and Detection of Terahertz Phonons In Gallium Arsenideto study the generation and decay mechanisms, and the scattering of dispersive high-frequency phonons in insulators and semiconductors.. The field is far from being mature; it is driven by the principal interest in excitations far from equilibrium. In addition there is the practical interest in stud

Phonon Imaging: Theory and Applicationsmal energy emanating from a point source of heat is strongly channelled into various directions in the crystal. This effect is simply caused by the elastic anisotropy of the crystal and is known as phonon focusing. Over the past several years phonon imaging techniques have been developed which graph

Surface Acoustic Wavesibration modes that are wavelike in directions parallel to the surface of the solid, but whose amplitudes decay exponentially with increasing distance into the solid from the surface, with a decay length that is of the order of the wavelength of the wave along the surface. The displacement vector of

Vibrational Energy Exchange Between Gases and Solidsonnection with aerospace research. Under rarified-gas conditions, where the mean free path of gas molecules is much larger than any characteristic surface length scale, the gas-surface interaction is no longer governed by boundary layer or bulk flow effects, but depends strictly on individual collis

The Gas/Phonon Interface: Desorption and other Phenomenample, the first splitting of the atom — J. J. Thomson’s discovery of the electron in 1896 — was accomplished when he realized he could improve the vacuum in his cathode ray tubes by baking them before they were sealed. Thomson’s insight may have been the first important application of thermal desorp
