GaAs Impurity Analysis

Gallium arsenide is a fascinating semiconductor with extensive use in the manufacture of infrared light-emitting diodes, laser diodes, solar cells and other optoelectronics. Learn more about it's quality control.

Besides Silicon, GaAs is one of the technically most important semiconductor materials, required for various devices. High purity or well-defined concentrations of, sometimes even wanted, impurities is crucial. FT-IR spectroscopy is a valuable tool for the analysis of such impurities. GaAs impurity analysis with Bruker FT-IR R&D spectrometers:

  • Quantification of Carbon in GaAs either at room temperature or at low temperature for improved sensitivity.
  • Low temperature Boron analysis in GaAs, sensitive to different Boron isotopes 10B and 11B.
