dj_mich, That is what my initial analysis made me think. "I did not know the substrate was that heavily doped but I can see the potential for disturbing the structure that had become so regular with Si28. The only caveat is the comment that heavy doping is still a trace element factor compared to the difference between pure and the natural isotope ratios in Si and that means the phonon disruption might be far lower as the doping affects the electrical properties and not the phonon properties which are a gross effect." Yes the holes/notholes etc made by dopants to be charge carriers are far smaller in effect than the gross levels of 80,000 PPM of natural Si, on the order of 1/100th the effect, although this intuitive answer may be wrong. As I see it the phonons like regular structures to travel within. Even a few hundred PPM might make places where the phonons bounce etc and in general interfere with each other out of all proportion to their presence in a similay way that trace dopants affect Si??
