The idea of “two-dimensional matter” is foreign to me.
“...using specially designed diamond anvils and neutrons to act as the probe of magnetism.”
I was just doing this at my apartment today...
Graphene is a zero-gap semiconductor, because its conduction and valence bands meet at the Dirac points. The Dirac points are six locations in momentum space, on the edge of the Brillouin zone, divided into two non-equivalent sets of three points. The two sets are labeled K and K’. The sets give graphene a valley degeneracy of gv = 2. By contrast, for traditional semiconductors the primary point of interest is generally Γ, where momentum is zero. Four electronic properties separate it from other condensed matter systems.
Im inventing a monopole magnet and AC battery. I’ll be rich I tells yah.
