  "abstract": "We use the differential 3ω method to directly measure the temperature dependent thermal conductivity for about 90 nm Mo0.78Si0.22 thin films. The measurements are performed in a closed-cycle cryostat to access the temperature range between 50 K and 300 K. The MoSi thin films are capped with Al2O3 and probed with a Pt wire. The results show that the thermal conductivity does not satisfy the Wiedemann-Franz law. This implies that thermal transport in MoSi is not dominated by electrons but by phonon-like excitations, contrary to what is assumed in many electro-thermal models of superconducting devices. We argue that this property might be related to the weak localization visible in the resistivity as a function of temperature curves of the superconductor.",
