FinFET can sometimes refer to a double-gated (side-gated) OR a tri-gated (top and side gated) device. Tri-gated is, as the name says, tri-gated. Tri-gated devices are superior because they have a larger surface area over which the gate contacts. Remember that the gate stack/semiconductor is...

A Schottky barrier is the potential barrier that prevents charge carriers from being injected from the semiconductor into the metal or vice versa. For an ohmic contact, you want a very low (or no) Schottky barrier because you desire a linear current with no potential barrier in either bias...

I'm unsure as to how well it would work for Cu, but quite often in our lab if we want to put down Au but have adhesion issues, we'll put down some Ti beforehand. Maybe 25-50nm?

Has anybody seen http://www.nature.com/nature/journal/v477/n7362/full/477005b.html"? I can't believe that a journal like nature is condoning the idea that unreasonable working hours for researchers are ok because that's just how things are going. What are some others' opinions on this article?

Winzer, do you mean high diffusivity? Heat capacitance is the amount of energy required to heat up the material by one degree, so we want that to be very low for it to heat quickly. We also want high thermal conductance so that the material heats quickly throughout the bulk. To summarize...

I'm doing four point probe measurements on contacts to semiconductor materials, and I'm trying to understand the effects of each type of resistance observed in probe measurements. Spreading resistance has been pretty elusive - nowhere seems to have a good definition of what it is except that it...
