He will present two joint theoretical and experimental studies of electronic transport in low-dimensional systems. Firstly, he will focus on the electronic transport along the anisotropic Ge(001)-c(4x2) surface with the use of two-probe scanning tunneling spectroscopy (2P-STS) and first-principles transport calculations. Secondly, he will present results for the electronic and transport properties of simple devices based on graphene nanoribbons (GNRs)  and 7-armchair-GNRs doped with boron [3,4], comparing our findings in the latter case with detailed STS experiments.
Daniel Sánchez-Portal is the Head of the Modelisation and Simulation group in the Materials Physics Center CSIC-UPV/EHU in San Sebastián. In 2005 he became a Tenured Researcher at CFM CSIC-UPV/EHU and a Research Professor in 2018. He was elected Fellow of the American Physical Society for his contribution to the development of methodologies for electronic structure calculations in 2016. His expertise and research interest cover the methodology of DFT based first-principles electronic structure calculations and its application to the study of nanostructures and surfaces. He is currently focused on the study of the electronic properties of covalent molecular networks, graphene nanostructures and other low-dimensional structures on surfaces in collaboration with several experimental groups, as well as to the application of TDDFT and other first-principles techniques to problems in nanoplasmonics and ultrafast electron dynamics at surfaces. He has published over 160 scientific papers with a significant impact.
