We report here a detailed study about the formation and self-organization of nanoscale structures during ion beam implantation at room temperature of 300 keV in Ge as a function of the ion fluence in the range between to . “Microexplosions” characterize the morphology of the swelled material; a random cellular structure consisting of cells surrounded by amorphous Ge ripples has been observed and studied in details by combining atomic force microscopy, scanning electron microscopy, and transmission electron microscopy.

Marco StampanoniThe key optical components of X-ray grating interferometry are gratings, whose profile requirements play the most critical role in acquiring high quality images. The difficulty of etching grating lines with high aspect ratios when the pitch is in the range of a few micrometers has greatly limited imaging applications based on X-ray grating interferometry. A high etching rate with low aspect ratio dependence is crucial for higher X-ray energy applications and good profile control by deep reactive ion etching of grating patterns. To achieve this goal, a modified Coburn–Winters model was applied in order to study the influence of key etching parameters, such as chamber pressure and etching power. The recipe for deep reactive ion etching was carefully fine-tuned based on the experimental results. Silicon gratings with an area of 70 × 70 mm2, pitch size of 1.2 and 2 μm were fabricated using the optimized process with aspect ratio α of ~67 and 77, respectively.

The photocatalytic efficiency of a thin-film TiO2-coated nanostructured template is studied by dye degradation in water. The nanostructured template was synthesized by metal-assisted wet etching of Si and used as substrate for the deposition of a thin film of TiO2 (10 nm thick) by atomic layer deposition. A complete structural characterization was made by scanning and transmission electron microscopies. The significant photocatalytic performance was evaluated by the degradation of two dyes in water: methylene blue and methyl orange. The relevance of the reported results is discussed, opening the route toward the application of the synthesized nanostructured TiO2 for water purification.
About Me
Lucia Romano obtained her PhD in Physics in 2006 from the University
of Catania (Italy). After completing a post-doc at the University of Florida
(Gainesville, USA), she was an assistant professor and researcher within the
Department of Physics of the University of Catania (Italy) between 2009 and 2022. In
2014, Lucia Romano joined the Paul Scherrer Institute and ETH Zurich in Switzerland
as a senior scientist to develop new methods of gratings' fabrication for
application in X-ray interferometric tomography. She has a background in materials
science for several kinds of applications, from the fundamentals of semiconductors
to nanotechnology, from microelectronics to environmental applications, and
X-ray optics. Lucia Romano has a long experience in semiconductors applied
research, ion beam modification of materials, materials characterization,
microfabrication, clean room operation, and equipment. At the moment, Lucia
Romano’s scientific research focuses on metal-assisted chemical
etching as a method for fabricating high-aspect-ratio structures in silicon. In her research, Lucia
Romano is addressing fundamental open questions about metal-assisted
chemical etching in order to fully explore the range of applications and the
limits of this processing.
