"MIT Physicists Discover Pencil Lead's Electronic Potential"
MIT physicists have discovered unique properties in graphite by stacking five graphene layers in a specific order, creating a material called pentalayer rhombohedral stacked graphene. This material can exhibit insulating, magnetic, or topological characteristics, which were previously unseen in natural graphite. The researchers used innovative nanoscale microscopy techniques to isolate and study this material, marking a significant advancement in material physics.
