We present a fabrication process of low-cost superlattices and simulations related with the heat dissipation on them. The influence of the interfacial roughness on the thermal conductivity of semiconductor/semiconductor superlattices was studied by equilibrium and non-equilibrium molecular dynamics and on the Kapitza resistance of superlattice's interfaces by equilibrium molecular dynamics. The non-equilibrium method was the tool used for the prediction of the Kapitza resistance for a binary semiconductor/metal system. Physical explanations are provided for rationalizing the simulation results.PACS68.65.Cd, 66.70.Df, 81.16.-c, 65.80.-g, 31.12.xv

This article conducts a detailed analysis of the concept of economic dependence and exploitative abuse based on how their treatment in competition law and economics and their enforcement in European case law have evolved. Although the theoretical roots of these concepts lie in economic theory, these issues have been ignored or considered only scantily in the context of competition law enforcement. An effects-based approach should take these problems into account and could provide insights into how to portray the impacts of these abuses. We draw on two examples-from the agri-food industries and the digital economy-of relevant economic dependence issues. This paper highlights the existence of a paradox: although industrial organization models provide relevant tools to characterize these abuses, assess their effects, and devise remedies, it seems that they are seldom used by competition law enforcers.
