Título: | From toothpaste to topological insulators and materials for valleytronics: the journeys of fluorinated tin |
Autor: | Barraza-López, Salvador; Rivero, Pablo; Yan, Jia-An; García-Suárez, Víctor M. CSIC ORCID ; Ferrer, Jaime CSIC ORCID | Fecha de publicación: | 2015 | Citación: | APS March Meeting 2015 | Resumen: | Tin fluoride has a vast literature. This material is stable in bulk form at room temperature and has commercial applications that include fluorinated toothpaste. Bulk tin fluoride has a pair of fluorine atoms bridging two tin atoms. In the recent past the electronic properties of 2D tin with honeycomb structure have been discussed thus generating a wealth of literature that emphasizes its non-topologically-trivial electronic properties due to the combination of a Dirac-like dispersion and a strong spin-orbit coupling given its large atomic mass. Nevertheless the stability of such freestanding structures has been contested recently. As it turns out, the most stable form of fluorinated tin does not possess a graphane-like structure either. In the most stable phase to be discussed here, fluorine atoms tilt away from (graphane-like) positions over/below tin atoms; in an atomistic arrangement similar to the one seen on their parent bulk structure. Electronic properties depend on atomistic coordination, and the most stable form of fluorinated tin does not possess non-trivial topological properties. Nevertheless it represents a new paradigm for valleytronics in 2D. | Descripción: | Resumen del trabajo presentado al American Physical Society March Meeting, celebrado en San Antonio, Texas (USA) del 2 al 6 de marzo de 2015. | URI: | http://hdl.handle.net/10261/137594 |
