A University of Washington-led team has discovered that, by stacking a sheet of graphene onto bulk graphite at a small twist angle (top), “exotic” properties present at the graphene-graphite interface (yellow) can bleed down into the graphite itself. Courtesy: Ellis Thompson
When two sheets of graphene are placed on top of each other and slightly twisted, their atoms form a
