Molybdenite Seen as Successor to Silicon
« on: 02/01/2011 05:11 pm »
Well, I don't know how useful it is to space tech, other than in electronics, but molybdenite has been shown to have superior qualities to silicon, leading to speculation that it could be contender as a successor:

I wonder if its properties might make it superior for solar power applications too? Molybdenite's bandgap properties are somewhere between GaAs and GaN, so that apparently opens it up for optical applications as well.

Carbon in its various forms I think is the perfect substitute for silicon.  It is directly above silicon in the periodic table meaning it has similar semi conducting properties.  Also it is very abundant. 

If you know much about electronics one of the biggest problems that chip makers deal with is heat, which limits the clock speed at which a computer can run without damaging its components.  Diamond has extremely good heat conductance and good heat tolerance meaning it could run at higher clock speeds without damage. 

Also graphite and graphene have similar advantages.
