Hot electrons, cold lattice: What slows current in twisted graphene?
Terahertz-Driven Hot Electron Transport in Twisted Bilayer Graphene Artist’s illustration of two graphene sheets rotated relative to one another, creating a moiré pattern. An incident terahertz radiation (red wave) deposits energy into the electronic system, producing a population of hot electrons (orange), depicted with short, irregular trajectories. Farther from the illuminated region, cooler electrons (blue) …
