We show that a large heat rectification is achievable if the thermal symmetry of the structure is broken and the central island can release energy to the phonon bath. The performance of the device is theoretically analyzed and, under the appropriate conditions, temperature differences up to ~200 mK between the forward and reverse thermal bias configurations are obtained below 1¿K, corresponding to a rectification ratio R~2000. The simplicity intrinsic to its design joined with the insensitivity to magnetic fields make our device potentially attractive as a fundamental building block in solid-state thermal nanocircuits and in general-purpose cryogenic electronic applications requiring energy management. 000070887 536__ $$9info:eu-repo/grantAgreement/EC/FP7/264034/EU/Quantum Nano-Electronics Training/Q-NET 000070887 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000070887 590__ $$a3.302$$b2014 000070887 591__ $$aPHYSICS, APPLIED$$b21 / 144 = 0.146$$c2014$$dQ1$$eT1 000070887 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000070887 700__ $$aMartínez-Pérez, M.J. 000070887 700__ $$aGiazotto, F. 000070887 773__ $$g104 (2014), [5 pp.]$$pAppl. phys. lett.$$tAPPLIED PHYSICS LETTERS$$x0003-6951 000070887 85641 $$uhttps://aip.scitation.org/doi/pdf/10.1063/1.4875917$$zTexto completo de la revista 000070887 8564_ $$s1171604$$uhttps://zaguan.unizar.es/record/70887/files/texto_completo.pdf$$yVersión publicada 000070887 8564_ $$s93794$$uhttps://zaguan.unizar.es/record/70887/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000070887 909CO $$ooai:zaguan.unizar.es:70887$$particulos$$pdriver 000070887 951__ $$a2019-05-29-11:44:09 000070887 980__ $$aARTICLE
