Hot electrons reveal electronic collisions may raise resistance in twisted graphene

When a material heats up, its electrical resistance often rises. The harder question is what, exactly, is getting in the way. The electrons carrying the current may be scattered by vibrations of the material's atomic lattice, known as phonons. They may also collide with one anoth This story matters for Science & Discovery readers tracking inventors. Reported by phys.org. Read the full original at the source link below.
