My research activity is centered on the physical properties of low dimensional systems. Currently I am working on carbon-based materials, such as carbon nanotubes or graphene nanoribbons, and semiconductor nanowires. I am interested in effects related to low dimensions, where defects and symmetries play a fundamental role. I have studied electronic and spin transport in nanosystems based on graphene and nanotubes, as well as different types of edges, topological defects and boundaries in these materials, relevant for nanoelectronics. Recently I have worked in the role of symmetry to achieve spin-polarized transport by solely using electric fields in carbon tubes and graphene ribbons. These results can be applied to other low-dimensional materials with spin-orbit interaction, of interest for the emerging field of spin-orbitronics.
I obtained my Ph.D. at Universidad Complutense de Madrid in 1993. Then I spent two years at UC Berkeley in a postdoctoral stay. After one year as a research associate at ICMM, I joined Universidad de Castilla-La Mancha, where I got a permanent position as an Associate Professor in 1999. In 2008 I returned to ICMM as Staff Scientist. In April 2015 I got clearance (acreditación) by ANECA that allows me to apply to full Professorship in Spanish Universities.
