Researchers explore electron-hole asymmetry in graphene

Researchers from Berkeley Lab’s Materials Sciences Division and the University of California, Berkeley, in collaboration with scientists at ISPC-CNR and Tsukuba's National Institute for Materials Science, have determined that interactions between electrons give rise to the effects observed when graphene is doped with electrons versus holes.A better understanding of this electron–hole asymmetry could lead to new ways of generating exotic material phases, including unconventional superconductivity.
