(Institut Català de Nanociència i Nanotecnologia) ; Valenzuela, Sergio O. (Institut Català de Nanociència i Nanotecnologia)
We investigate hot carrier propagation across graphene using an electrical nonlocal injection/detection method. The device consists of a monolayer graphene flake contacted by multiple metal leads. Using two remote leads for electrical heating, we generate a carrier temperature gradient that results in a measurable thermoelectric voltage V across the remaining (detector) leads. [...]

Graphene is an excellent material for long-distance spin transport but allows little spin manipulation. Transition-metal dichalcogenides imprint their strong spin-orbit coupling into graphene via the proximity effect, and it has been predicted that efficient spin-to-charge conversion due to spin Hall and Rashba-Edelstein effects could be achieved.

Supercapacitors are called to play a prominent role in the newly emerging markets of electric vehicles, flexible displays and sensors, and wearable electronics. In order to compete with current battery technology, supercapacitors have to be designed with highly conductive current collectors exhibiting high surface area per unit volume and uniformly coated with pseudocapacitive materials, which is crucial to boost the energy density while maintaining a high power density.

17 p, 868.1 KB Impact of vacancies on diffusive and pseudodiffusive electronic transport in graphene / Cresti, Alessandro (Université Grenoble Alpes) ; Louvet, Thibaud (Institut Català de Nanociència i Nanotecnologia) ; Ortmann, Frank (Institut Català de Nanociència i Nanotecnologia) ; Dinh, Van Tuan (Institut Català de Nanociència i Nanotecnologia) ; Lenarczyk, Pawel (Institut Català de Nanociència i Nanotecnologia) ; Huhs, Georg (Centre Nacional de Supercomputació) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia)
We present a survey of the effect of vacancies on quantum transport in graphene, exploring conduction regimes ranging from tunnelling to intrinsic transport phenomena. Vacancies, with density up to 2%, are distributed at random either in a balanced manner between the two sublattices or in a totally unbalanced configuration where only atoms sitting on a given sublattice are randomly removed.

Hard corona (HC) protein, i. e. , the environmental proteins of the biological medium that are bound to a nanosurface, is known to affect the biological fate of a nanomedicine. Due to the size, curvature, and specific surface area (SSA) 3-factor interactions inherited in the traditional 3D nanoparticle, HC-dependent bio–nano interactions are often poorly probed and interpreted.
