| contents | Transition metal dichalcogenide (TMD) heterostructures have emerged as promising platforms for realizing tunable Bose-Fermi mixtures. Their constituents are fermionic charge carriers resonantly coupled to long-lived bosonic interlayer excitons, allowing them to form trion bound states. Such platforms promise to achieve comparable densities of fermions and bosons at low relative temperatures. Here, we predict the transport properties of Bose-Fermi mixtures close to a narrow solid-state Feshbach resonance. When driving a hole current, the response of doped holes, excitons, and trions are significantly modified by the resonant interactions, leading to deviations from the typical Drude behavior and to a sign change of the exciton drag. Our results on the temperature-dependent resistivities demonstrate that interaction effects dominate over established conventional scattering mechanisms in these solid-state Bose-Fermi mixtures. |
