Apparent Kondo effect in Moiré transition metal dichalcogenide bilayers: Heavy fermions versus disorder

Apparent Kondo effect in Moiré transition metal dichalcogenide bilayers: Heavy fermions versus disorder

A recent work by Zhao et al. [1] reports the realization of a synthetic Kondo lattice in a gate-tunable Moir\'e TMD bilayer system. The observation of a Kondo lattice is supported by a plateau (or dip, depending on filling) in the temperature dependence of the resistivity $\rho(T)$ around $T^*\sim 40~$K, …
