[NewCandle] Image magnetic monopole charge

[Nick Reiter]

Hey Keith and all,

Late this afternoon, I snipped out a couple of Peltier chip "members" - one of each, p and n (although I do not really know which is which!)

This was from one of the larger burned out Melcor chips that would have given at least some force effect back in the day.  I put both of them in the SEM and looked at their composition with EDS.

They are indeed mainly Bi and Te, however I was surprised to see about 2% Se in both, and about .3% Sn.  The main difference between "right" and "left" (n-p? p-n?) couple halves was in the stoichiometry of Bi to Te.  The one leg seemed to be about 2:3 Bi to Te, but the other was Te deficient.

No problem with trying some of this Peltier chip material obviously, but I do believe I want to also make some Bi2Te3 from the high purity Bi and Te materials I have, in a reaction ampoule.  I can then just go ahead and diffuse .67% at. Sn into the melt.
