We report on the temperature dependence of the mobility of the two-dimensional electron gas in a variable density AlGaN/GaN field effect transistor, with carrier densities ranging from 0.4x1012cm-2

Acoustic Properties of Longitudinal Displacement in Vocal Cord Vibration By K. ISHIZAKA and J. L.

When a collimated light beam traverses a collimated high-frequency acoustic beam, it is possible for the acoustic beam to scatter light into a single, well-defined angle (into a number of well-defi

Automated Condition Monitoring of machines typically involves the detection and diagnosis of developing defects.

A monostatic Doppler sodar together with a 63-m meteorological tower located in Georgia is used to probe the lower atmosphere that effects propagation in terrestrial line-of-sight microwave transmi

The acoustic properties of single crystals of the high temperature superconductor YBa sub 2 Cu sub 3 O sub 7 have been measured at temperatures between 0.1 and 300K for frequencies near 10 sup 3 an

While the surface Rayleigh phonon is normally the dominant long wavelength acoustic feature for a film on a substrate, the rich spectrum of higher order excitations also offers novel possibilities

This letter reports picosecond laser-based measurements of acoustic waveguiding in a thin film of nanoporous silica (similar to silica aerogel or xerogel) on silicon for wavelengths between 2.5 and
