SignificanceWhen two sheets of graphene are twisted to the magic angle of 1.1<sup>∘</sup>, the resulting flat moiré bands can host exotic correlated electronic states such as superconductivity and ferromagnetism. Here, we show transport properties of a twisted bilayer graphene device at 1.38<sup>∘</sup>, far enough above the magic angle that we do not expect exotic correlated states. Instead, we see several unusual behaviors in the device's resistivity upon tuning both charge carrier density and ...[more]
