9 p, 1.3 MB Thermal conductivity in disordered porous nanomembranes / Sledzinska, Marianna (Institut Català de Nanociència i Nanotecnologia) ; Graczykowski, Bartlomiej (Max Planck Institute for Polymer Research) ; Alzina, Francesc (Institut Català de Nanociència i Nanotecnologia) ; Melia, Umberto (Universitat Politècnica de Catalunya. Departament d'Enginyeria de Sistemes, Automàtica i Informàtica Industrial) ; Termentzidis, Konstantinos (Centre National de la Recherche Scientifique (França)) ; Lacroix, David (Centre National de la Recherche Scientifique (França)) ; Sotomayor Torres, Clivia M. (Institut Català de Nanociència i Nanotecnologia)
In this work we study the effects of disorder on the thermal conductivity of porous 100 nm thick silicon membranes, in which the size, shape and position of the pores were varied randomly. Measurements using two-laser Raman thermometry on both non-patterned and porous membranes revealed more than a 10-fold reduction of the thermal conductivity compared to that of bulk silicon and a six-fold reduction compared to non-patterned membranes for the sample with random pore shapes.

15 p, 4.0 MB Metamirrors Based on Arrays of Silicon Nanowires with Height Gradients / Otte Ortiz, Marinus Albertus (Institut Català de Nanociència i Nanotecnologia) ; García Martín, Antonio (Instituto de Microelectrónica de Madrid) ; Borrisé, Xavier (Institut Català de Nanociència i Nanotecnologia) ; Sepúlveda, Borja (Institut Català de Nanociència i Nanotecnologia)
Arrays of silicon nanowires with height gradients fabricated using metal-assisted chemical etching act as tunable metamirrors enabling light focusing the reflected light in arbitrary shapes. Metamirrors with non-cylindrical nanowires can simultaneously focus the reflected light and induce strong polarization conversion effect.

Studying thermal transport at the nanoscale poses formidable experimental challenges due both to the physics of the measurement process and to the issues of accuracy and reproducibility. The laser-induced transient thermal grating (TTG) technique permits non-contact measurements on nanostructured samples without a need for metal heaters or any other extraneous structures, offering the advantage of inherently high absolute accuracy.

GaAs nanowire arrays on silicon offer great perspectives in the optoelectronics and solar cell industry. To fulfill this potential, gold-free growth in predetermined positions should be achieved. Ga-assisted growth of GaAs nanowires in the form of array has been shown to be challenging and difficult to reproduce. [...]
