Dopant Spatial Distributions: Sample Independent Response Function And Maximum Entropy Reconstruction

, 1997
We demonstrate the use of maximum entropy based deconvolution to reconstruct boron spatial distribution from the secondary ion mass spectrometry (SIMS) depth profiles on a system of variously spaced boron $\delta$-layers grown in silicon.

Auger electron spectroscopy, secondary ion mass spectroscopy and optical characterization of a-C-H and BN films [PDF]

The amorphous dielectrics a-C:H and BN were deposited on III-V semiconductors. Optical band gaps as high as 3 eV were measured for a-C:H generated by C4H10 plasmas; a comparison was made with bad gaps obtained from films prepared by CH4 glow discharges ...

Development and Application of a Mass Spectrometry Platform for On-line Monitoring of Ion Products Generated by High-Voltage Air Discharge

Zhipu Xuebao
Indoor air pollution poses significant health risks due to particulate matter (PM) and gaseous pollutants. Air negative ions (NAIs) generated by high-voltage discharge can effectively remove PM, but require precise monitoring to optimize performance and ...
