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.
