Four commercial samples of tungsten hexafluoride were analyzed for purity by Fourier transform mass spectrometry.
We review recent advances in the pursuit of photon-efficient modulation and detection for optical communications.
In the past several years, there has been a concerted effort to harmonize international standards for emission limits and associated measurement techniques.
The pyrolytic conversion of an organosilsequioxane (Owens-Illinois resin GR650) to SiO2 is characterized by ir spectroscopy, thermogravimetry and evolved gas analysis (line-of-sight mass spectrosco
1.1 Quality assurance The responsibility of the Bell Laboratories Quality Assurance Center (QAC) is "to ensure that the communications products designed by Bell Laboratories and bought by Bell Syst
Since its invention at Bell Labs in the mid-nineties, the quantum cascade laser (QCL) has evolved rapidly to become a viable commercial alternative to other solid-state mid-infrared light sources.
Under its classical form, the envelope function theory generally used to calculate electronic properties of semiconductor heterostructures is supersymmetric >>.
Experimental discovery of a quantized Hall state at 5/2 filling factor presented and enigmatic finding in an established field of study that has remained an open issue for more than twenty years.
The quantum Hall effect (QHF) is a new physical phenomenon.
This lecture reviews some recent developments in the experimental aspects of the quantum Hall effect (QHE) such as the observation of the integral QHE in quasi three-dimensional systems, the magnet
