      abstract     = {Heat transport plays a critical role in modern batteries,
                      electrodes, and capacitors. This is caused by the ongoing
                      miniaturization of such nanotechnological devices, which
                      increases the local power density and hence temperature.
                      Even worse, the introduction of heterostructures and
                      interfaces is often accompanied by a reduction in thermal
                      conductivity, which can ultimately lead to the failure of
                      the entire device. Surprisingly, a fundamental understanding
                      of the governing heat transport processes even in simple
                      systems, such as binary particle mixtures is still missing.
                      This contribution closes this gap and elucidates how
                      strongly the polydispersity of a model particulate system
                      influences the effective thermal conductivity across such a
                      heterogeneous system. In a combined experimental and
                      modeling approach, well‐defined mixtures of monodisperse
                      particles with varying size ratios are investigated. The
                      transition from order to disorder can reduce the effective
                      thermal conductivity by as much as $≈50\%.$ This is caused
                      by an increase in the thermal transport path length and is
                      governed by the number of interparticle contact points.
                      These results are of general importance for many particulate
                      and heterostructured materials and will help to conceive
                      improved device layouts with more reliable heat dissipation
                      or conservation properties in the future.},
