Abstract: Modern electronic devices comes from a double evolution. On one hand the miniaturization techniques have reduced the traditional devices to the microscopical scales. Such approach is called top-down. On the other hand, the researching in multidisciplinary fields has created novel devices, natively nanostructured. Carbon nanotubes, nanowire and quantum dots are examples of such devices, designed following an approach called bottom-up. These two evolutive lines are converging in strongly heterogeneous devices, whose features are due to both micro and macroscopical elements. Hence, there is the need of CADs to employ models acting at different scales in the same simulation. Such a model is called multiscale model. Multiscale models involve several fields, ranging from fluid dynamics to electronic transport. In this work we deal with heating and heat dissipation in a multiscale domain. In particular, we investigate the Joule’s effect at the macro, meso and nanoscales. We start...
