Trace Element Measurements with Synchrotron Radiation

Looking at trace impurities on silicon wafers with synchrotron radiation.

Figure 1. TXRF spectrum of a clean Si wafer surface showing 6.4x10 atoms/cm Fe and 2.6x10 atoms/cm Cu. The Cl is a residue from the HCl solution used to clean the wafer surface and the Ag is a artifact from the particular collimator used in these studies. Other features seen in the spectrum are the Si substrate peak, the scatter peak at 11.2 keV and the escape peak at 9.4 keV. Looking at Trace ...

Infrared Science with Synchrotron Radiation

Synchrotron radiation is best known as a source of X-rays, but it is also a source for VUV to soft-Xrays photons. However, it was realised in the early 90’s that this source can also be exploited in the infrared energy domain. Even if in some frequency regions (roughly 30 microns and below) the total photon flux emitted by the synchrotron source remains inferior to that of a thermal source, the...
