Dario A. Bahamon Position: Associate Professor Area of interest: Theory Email: firstname.lastname@example.org Office: 407 Phone: +55 11 2766-7526 Dario earned a BSc degree in electrical engineering and physics (2000) from Los Andes University in Bogota, Colombia; a PhD in physics (2011) from Campinas State University (UNICAMP) in Campinas, Brazil. From 2012 to 2014 he was a research fellow at the Graphene Research Centre of the National University of Singapore. In 2014 he joined the Graphene and Nano-Materials Research Center-Mackgrafe of the Mackenzie Presbyterian University.Research interest: Electronic transport in 2D Material My research aims to understand the physical aspects, envisage applications and computer simulation of electronic transport in 2D materials and devices of reduced dimensions. We combine phenomenological, scattering theory and numerical (Green’s function technique) methods to unveil the role of disorder (chemical, magnetic impurities, vacancies, defects, edges), magnetic fields and strain on the charge and spin density distribution, conductance and current. Straintronics: The extreme mechanical resilience of the carbon bonding in graphene, when intertwined with its unusual Dirac-fermion electronic degrees of freedom, makes it possible to modify the electronic characteristics by means of deformations in completely novel ways in a condensed-matter setting. In this context, our interest lies in characterizing the intrinsic electronic transport features arising from the interplay of geometry, size and mechanical deformation.

Manipulation of charge and spin of the electron is one of the most promising areas in nanotechnology; pure spin currents could be generated and controlled by electric means in a new class of electronic devices. In 2D materials the surface is completely exposed, thus their electronic properties can be modificated by adsorbed chemical species or by the substrate. Specially, non-magnetic adatoms or proximity to gold clusters have locally increased the Spin Orbit Coupling (SOC), in graphene, generating pure spin currents. Our research in this area focuses on detection and control of these spin currents in multi-contact devices. We are developing and applying different recursive techniques as well as sparse matrix solvers to extend the Non Equilibrium Green’s Functions (NEGF) technique to multi-contact electronic devices.
