We introduce an effective tight-binding model to discuss penta-graphene and present an analytical solution. This model only involves the ?-orbitals of the sp2-hybridized carbon atoms and reproduces the two highest valence bands. By introducing e[...]texto impreso
Density functional theory calculations reveal the existence of different correlated-electron ground states in (111)-oriented n-type LaAlO_(3)/SrTiO_(3) symmetric superlattices. They can be tuned by selecting the SrTiO3 thickness, and range from [...]texto impreso
Muñoz, M. C. ; Chico, L. ; López-Sancho, M. P. ; Beltrán Finez, Juan Ignacio ; Gallego, S. ; Cerdá, J. | IOP publishing ltd | 2006The symmetry underlying the geometric structure of materials determines most of their physical properties. In low dimensional systems the role of symmetry is enhanced and can give rise to new phenomena. Here, we report on unexpected magnetism in[...]
