Hot electrons reveal electronic collisions may raise resistance in twisted grapheneWorldPing

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.
