Graphene

Post by ladajo »

I am sure we talked about this before, but the parallels to "polywell" development were too tempting.

"The material itself does not have a band gap, an essential property [meaning that graphene cannot stop conducting and be 'switched off', making it unusable in this way]. The applications of graphene and the application of silicon are in different domains."
Problem or opportunity? Graphene "semiconductors" have a tunable band gap.

So far in the 0 to 100 mv range. Germanium is 300 mv. Silicon is 600 mv. And IIRC SiC comes in at 1,200 mv.

SiC was 1200mv?

I recall when Sandia(?) came up with it. I remember thinking hard on how to start up a supply company for it. The heat resistance is huge.

For Graphene, I am going to have to do a little more research. But I see its utilility up front.

2,360 to 3,230 mv depending on structure. So I remembered it wrong.
