Growth of nanowire arrays from micron-feature templates

Anna Fontcuberta i Morral, Gaëtan Bernard, Martin George Friedl, Wonjong Kim, Dmitry Mikulik, Lea Ghisalberti, Pablo Romero Gómez, William Craig Carter, Christian André Jürgensen

Here, we present a two-step annealing procedure to imprint nanofeatures on SiO2 starting from metallic microfeatures. The first annealing transforms the microfeatures into gold nanoparticles and the second imprints these nanoparticles into the SiO2 layer w ...

Graph fragmentation problem: analysis and synthesis

Manuel Francesco Aprile, Pablo Romero Gómez

Vulnerability metrics play a key role in the understanding of cascading failures and target/random attacks to a network. The graph fragmentation problem (GFP) is the result of a worst-case analysis of a random attack. We can choose a fixed number of indivi ...

Extraction of p-n junction properties and series resistance in GaAs nanowire-based solar cells using light concentration

Anna Fontcuberta i Morral, Dmitry Mikulik, Pablo Romero Gómez, Ian Nachemson

Series resistance in solar cells limit their maximum conversion efficiency and thus should be minimized. Generally, such losses originate from deficiencies at the contact or absorber level. Quantifying them is the first step for tackling its reduction. In ...

Photophysics behind highly luminescent two-dimensional hybrid perovskite (CH3(CH2)2NH3)2(CH3NH3)2Pb3Br10 thin films

Anna Fontcuberta i Morral, Luca Francaviglia, Pablo Romero Gómez

Two-dimensional (2D) Ruddlesden–Popper perovskites have emerged as a new class of hybrid materials with high photoluminescence and improved stability compared to their three-dimensional (3D) counterparts. Studies of the photophysics of these new 2D perovsk ...

Managing the solar spectrum at sub-wavelength scales: nanowire enabled new PV concepts (Conference Presentation)

Anna Fontcuberta i Morral, Pablo Romero Gómez

III-V semiconductor nanowires (NWs) are promising building blocks for next generation solar energy conversion at low cost. NW ensembles constitute a new class of metamaterial, where the optical properties of the array are tuned by the individual NW type, g ...
