Ihinger and Zink used high-resolution infrared spectroscopy to map impurity
concentrations across different slices of a gem-quality quartz crystal.
alloys; * diluting the impurity
by adding impurity
AEC's second test was conducted under more controlled conditions, which reduced this impurity
by approximately 95%.
Experimenters can duplicate the effect by varying the magnetic field applied to a single wire -- a change equivalent to randomly shifting the positions of the impurity
Scientists at Bell Labs, the research and development arm of Lucent Technologies (NYSE:LU), have found a way to peer deep inside a semiconductor and create an image of a single impurity
atom in silicon.
The British scientists, however, have not needed to dope their material because it has picked up some trace impurity
in the processing, Friend says.
The objective of drilling is to identify the highest grade zone with the lowest impurity
Two new reports of experiments done on copper-oxide systems support the idea that adding an impurity
, such as strontium to lanthanum copper oxide, disturbs the magnetic interaction between copper atoms.
The analyzer takes advantage of an entire spectrum of impurity
emissions to provide a powerful and adaptable, cost-effective means of continuous multiple impurity
Each specific sample has a conductance that goes with that impurity
configuration," Skocpol says.
Also, design work is near completion for a third generation reactor capable of handling larger wafers with higher impurity
In conventional gallium arsenide materials, the electrons sit in the same volume as the impurity
Consequently, the Company's relatively new management has focused over its short (less than two years) tenure, much of its emphasis on eliminating this impurity
Because these secondary X-rays are characteristic of the particular atom that emitted them, a properly positioned detector can measure a range of X-ray wavelengths simultaneously and use this to calculate the relative concentrations of different metallic impurity
atoms on the surface.
