Current can literally blow copper interconnects away, but graphene could keep them intact Image: Stanford University Images: Stanford University Death By Electromigration: Copper interconnects are now so narrow that current can cause a break by knocking atoms out of place. Most of the hand-wringing over the fate of Moore’s Law focuses on the ever-shrinking silicon(…)
