Graphene and electric transport properties in graphene-superconductor interfaces

Graphene is a two dimensional carbon structure, which possesses unusual electronic properties, whose electrons are described by the Dirac equation. This material allows to establish an analogy between condensed matter and particle physics. The graphene production a few years ago has encouraged a gre...

Este material permite establecer una analogía entre la física de partículas y la materia condensada. La obtención del grafeno hace pocos años ha incentivado una gran cantidad de trabajos experimentales y teóricos con el propósito de poder entender y manipular sus propiedades. Actualmente se han investigado diferentes junturas compuestas por interfases grafeno-superconductor, a saber: GS, GIS, SGS, IGS (I:aislante, G: grafeno, S: superconductor), en las cuales la existencia de reflexiones de Andreev normales y especulares ha cobrado gran interés. En este trabajo hacemos una introducción a las propiedades básicas del grafeno y una breve revisión sobre trabajos acerca de interfases grafeno-superconductor.application/pdfspaUniversidad Nacional de Colombia, Bogotáhttp://revistas.unal.edu.co/index.php/momento/article/view/34559Universidad Nacional de Colombia Revistas electrónicas UN MOMENTO - Revista de FísicaMOMENTO - Revista de FísicaMOMENTO - Revista de Física; núm. 42 (2011); 77-96 0121-4470Manjarrés, Diego and Gómez, Shirley and Herrera, William (2011) Graphene and electric transport properties in graphene-superconductor interfaces.
