Slashdot Mirror
Another Step Towards Graphene Semiconductors
derGoldstein writes "Ars has an article up about the two latest 'papers demonstrating that, if you change the way the graphene stacks, you obtain a voltage-controlled bandgap ... Between these two papers, a fairly complete understanding of the bandgap behavior in three-layer graphene has been obtained, leaving only the challenge of making the stuff.'"
Congratulations, you just ruined my day!
Why is this marked troll? Is suddenly a healthy does of reality mean your a troll on Slashdot?! Look graphene is an incredibly rare substance and we have yet to figure out how to manufacture large amounts of the stuff to overcome that rare part. There are a lot of papers out there that address all the amazing stuff that can be done with graphene but until there is an appreciable amount of the stuff its all pipe dreams.
So I fail to see why, when someone points out this fact, they get modded troll? This is not to say the technology is flawed or a bad idea or what-have-you, it's just outside of our reach and until we overcome the production problem, it will remain so. This draws so many parallels to the current debate of oil as the basis of our motor fuels. I love the idea of electric cars, but we're not totally there yet. There is a lot that needs to be figured out, infrastructure, manufacturers, TOC, energy production... Without getting too off-topic here, the same applies. The technology sounds awesome but we have yet to make it viable. Sometimes I think it just infuriates Slashdotters that no matter how clever humanity gets, we still have to convince the idiots to go along with us as well or we get zero traction on things.
to mods : well I thought it was funny
