Distribution of defects and impurities in gallium arsenide wafers after surface gettering
Gettering of defects and impurities in GaAs using a heat treatment (HT) of the yttrium-coated wafers has been investigated. The gettering has been established to be of a volume character. That has allows [...]
Precipitation in low temperature grown GaAs
The precipitation of arsenic in GaAs epitaxially grown at low temperature (LT GaAs) has been studied as a function of the post-growth annealing temperature by three independent methods: transmission electron microscopy (TEM), Raman scattering, and for the first time [...]
We can offer semiconductor wafers with X-ray diffraction (XRD) diagram. So what is XRD? XRD technology is a research method to obtain information such as the composition of the material, the structure or morphology of the atoms or molecules in the material by analyzing [...]
