[NewCandle] Topological Insulators

[Nick Reiter]

Hi Keith,

Having worked in CdTe for about 17 years, I guess I have a natural penchant for chalcogenides.  But more to the point, you will recall the oddball effect I chased around about 8 years ago whilst on Vo, and then followed up with a bit more recently, wherein I was seeing what appeared to be a directed force effect on a Peltier chip under power, that acted congruently in the direction of heat pumping.  That effect remains one of the very few that still holds up to some of the best artifact reduction I could toss at it.  However it also remains capricious as hell, with respect to some chips showing the effect much more clearly than others.  Well, those devices typically all use Bi2Te3 n and p doped couples.

Plus I'm a grand sucker for any of the three thermoelectric effects, and Bi2Te3 is just so there for them, in my glee for Z.

I need to re-read this new paper... I missed the monopole reference!  as Zippy would exclaim, "Yow!"
