Coloquio de Física - Preparación y caracterización de películas delgadas de compuestos pseudobinarios a-(SiC)x(AlN)1-x dopadas con tierras raras usando RF-magnetron sputtering

   14 de Abril de 2011
...egion due to their large band-gap (3 eV and 6.2 eV). The pseudobinary system (SiC)1-x(AlN)x ensures the adjustment of the desired ban...system stands out due to its easy and therefore inexpensive preparation. Thin amorphous (SiC)1-x(AlN)x -films are prepared and investigated at the PUCP (Pontificia Universidad Católica del Perú) using dual-rf-magnetron-sputtering. The starting materials are high purity, (poly)crystalline SiC and AlN targets prepared at the university of Erlangen which ensure in contrast to commercially available ceramic targets the completion of amorphous films with semiconductor quality. First films have been produced and the results will be presented. The band-gap is determined by means of optical transmission spectroscopy and the composition of the material by EDX-measurement. For the limiting cases, i.e., x=0, SiC and x=1, AlN rare earth doping (Tb, Eu, Dy) have been performed and their thermal activated emission has been studied by cathodoluminescence. The current research of the laboratory in materials science is part of the collaboration between the PUCP and the university of Erlangen-Nürnberg supported by the DFG (Deutsche Forschungsgemeinschaft)....

Lista   HD   Coloquio de Física - Frontiers in super resolution microscopy: bio-imaging

   27 de Marzo de 2019
...nente: Zeev Zalevsky (Bar-Ilan University, Israel) Digital imaging systems and the human vision ...system have limited capability to separate spatial features. Therefore, their imaging resolution is limited. The reasons for this limitation are related to the effects of diffraction, i.e., the finite dimensions of the imaging optics, the geometry of the sensing array and its sensitivity, and the position of the object itself, which may be out of focus. In this talk I will first present novel photonic approaches and means to overcome these limitations and eventually allow us to have super-resolved imaging systems. Then I will demonstrate a novel, extended depth-of-foc......
