8 p, 722.6 KB Spatial mapping of exciton lifetimes in single ZnO nanowires / Reparaz, Juan Sebastián (Institut Català de Nanociència i Nanotecnologia) ; Callsen, Gordon (Technische Universität Berlin) ; Wagner, Markus R. (Institut Català de Nanociència i Nanotecnologia) ; Güell, Frank (Universitat de Barcelona. Departament d'Electrònica) ; Morante, Joan Ramon (Institut de Recerca en Energia de Catalunya) ; Sotomayor Torres, Clivia M. (Institut Català de Nanociència i Nanotecnologia) ; Hoffmann, Axel (Technische Universität Berlin)
We investigate the spatial dependence of the exciton lifetimes in single ZnO nanowires. We have found that the free exciton and bound exciton lifetimes exhibit a maximum at the center of nanowires, while they decrease by 30% towards the tips. [...]

(Institut Català de Nanociència i Nanotecnologia)
We describe and discuss the optical design of a diffractometer to carry out in-line quality control during roll-to-roll nanoimprinting. The tool measures diffractograms in reflection geometry, through an aspheric lens to gain fast, non-invasive information of any changes to the critical dimensions of target grating structures. [...]

(Institut Català de Nanociència i Nanotecnologia)
We report on the reduction of the thermal conductivity in ultra-thin suspended Si membranes with high crystalline quality. A series of membranes with thicknesses ranging from 9 nm to 1. 5 μm was investigated using Raman thermometry, a novel contactless technique for thermal conductivity determination. [...]
