17.The integrated absorption coefficient is proportional to the concentration of absorbing centers. However, the absorbance, determined by experiment, is proportional to the product of the absorption coefficient times the thickness of the absorbing layer. The integrated absorbance, therefore, is proportional to the concentration of centers times the thickness of the absorbing layer, that is, to the areal density.
18.If molecules were introduced into the Si, they would not be easily seen by IR spectroscopy because of the weakness of their vibrational absorption. We have annealed a few samples at 200 °C where the molecule would be dissociated and give rise to impurity-H complexes. No new PtH complexes were found in these test experiments, leading us to conclude that any concentration of molecules is smaller that the concentration of PtH complexes we have detected.
19.An estimate of the concentration of released H made from the change in the IR intensity of the Si–H absorption intensity for the and the calibration given by, W. A. Lanford and M. J. Rand, J. Appl. Phys. 49, 2473 (1978), yields a similar result.
