Signatures of hot carriers and hot phonons in the re-entrant metallic and semiconducting states of Moiré-gapped graphene

Significant attention has been devoted to understanding the low-electric-field properties of carriers in moiré graphene, but high-electric-field transport has not been as well explored. Here, the authors find non-monotonic transport behavior at moiré minigaps due to competition between inter-band tunneling and coupling to out-of-equilibrium phonons.
