Re: resistivity versus temperature

[Joseph Bellina <jbellina@SAINTMARYS.EDU>]

I'm getting into this late as usual.  Another interesting effect is the
resistivity of thin metal films.  Similar to Al Overhauser's work, you
can watch thin films anneal by watching the resistance as a function of
temperature. Further the final resistivity does not match the bulk value
because of scattering at the surfaces of the thin film.
