High power density energy harvesting devices based on the anomalous Nernst effect of Co/Pt magnetic multilayers
Guillermo Lopez-Polin, Hugo Aramberri, Jorge Marques-Marchan +4
The anomalous Nernst effect (ANE) is a thermomagnetic phenomenon with potential applications in thermal energy harvesting. While many recent works studied the approaches to increas…
The effect of rippling on the mechanical properties of graphene
Guillermo Lopez-Polin, Cristina Gomez-Navarro, Julio Gomez-Herrero
Graphene is the stiffest material known so far but, due to its one-atom thickness, it is also very bendable. Consequently, free-standing graphene exhibit ripples that has major eff…
Improved graphene blisters by ultrahigh pressure sealing
Y. Manzanares-Negro, P. Ares, M. Jaafar +3
Graphene is a very attractive material for nanomechanical devices and membrane applications. Graphene blisters based on silicon oxide micro-cavities are a simple but relevant examp…
Tailoring the thermal expansion of graphene via controlled defect creation
Guillermo López-Polín, Maria Ortega, J. G. Vilhena +5
Contrary to most materials, graphene exhibits a negative thermal expansion coefficient (TEC), i.e it contracts when heated. This contraction is due to the thermal excitation of low…
Environmental Effects in Mechanical Properties of Few-layer Black Phosphorus
Miriam Moreno-Moreno, Guillermo Lopez-Polin, Andres Castellanos-Gomez +2
We report on the mechanical properties of few-layer black phosphorus (BP) nanosheets, in high vacuum and as a function of time of exposure to atmospheric conditions [1]. BP flakes…
