Piezoelectric thin-film AIN has great potential for on-chip devices such as Thin-Film Resonator (TER) based bandpass filters.
We determine the density-dependent electron mass m({*}) in two-dimensional electron systems of GaAs/AlGaAs heterostructures by performing detailed low-temperature Shubnikov-de Haas measurements.
We discuss the relationship between facet reflectivity and gain bandwidth in semiconductor optical amplifiers and present the first high resolution measurements of the gain spectrum of InGaAsP 1.
Results are reported on the magnitude of the large-scale DC Earth potential using measurements made on a section of a recently laid transatlantic telecommunications cable.
We have performed extensive measurements upon commercial CDMA2000 networks supporting predominantly voice services using a proprietary monitoring tool called Celnet Xplorer.
We present the results of some measurements of earth lighting made with the functional unit of the Galileo probe RF lighting experiment. The frequency range used is ~100 Hz - 100 kHz.
We examine the temperature dependence of the bubble phase using the resonance in the real diagonal conductivity, Re{[}sigma(xx)], discovered recently by Lewis et al. (Phys. Rev. Lett.
A new method of fabricating charge coupled devices1 (CCD) using the technique of undercut isolation has been reported recently.
T h i s paper has a very direct bearing upon the p u m p i n g or exhausting of the v a c u u m tubes used in telephone repeaters a n d similar thermionic tubes.
Decades of classification research yielded many useful classifiers. Yet their accuracies on many practical applications remain far from perfect.
