Nonlinear heat transport in superlattices with mobile defects Jou i Mirabent, David, Restuccia, Liliana University of Messina Heat transport Extended thermodynamics Mobile defects Defect engineering Thermal Transistor Superlattices We consider heat conduction in a superlattice with mobile defects, which reduce the thermal conductivity of the material. If the defects may be dragged by the heat flux, and if they are stopped at the interfaces of the superlattice, it is seen that the effective thermal resistance of the layers will depend on the heat flux. Thus, the concentration dependence of the transport coefficients plus the mobility of the defects lead to a strongly nonlinear behavior of heat transport, which may be used in some cases as a basis for thermal transistors. 2019 Article https://ddd.uab.cat/record/216819 urn:10.3390/e21121200 urn:oai:ddd.uab.cat:216819 urn:wos_id:000507375900068 urn:altmetric_id:72475506 urn:scopus_id:85079156421 urn:pmid: urn:pmc-uid:7514545 urn:pmcid:PMC7514545 urn:oai:pubmedcentral.nih.gov:7514545 urn:pmid: urn:oai:egreta.uab.cat:publications/d55d8c6d-714f-46a5-b892-4681528537ad eng Entropy ; Vol. 21 (2019), p. 1-13 open access Aquest document està subjecte a una llicència d'ús Creative Commons.
