Silicon Carbide (SiC) can be proposed as an alternative to Silicon to improve the power of the electrical devices and reduce the electricity consumption, in all areas of electronics. My research activity is promoted by the “CHALLENGE” project (included in the Horizon-2020 program), whose aim is to develop cubic Silicon Carbide (3C-SiC) hetero-epitaxially grown on silicon compliance substrates, for sustainable wide band-gap power device. In particular, I study how different patterned substrates can affect the density of anti-phase boundary (APB) defects, as a function of various SiC thickness deposition. Characterizations of several samples, different for thicknesses of SiC growth on different patterned substrates, are performed by means of scanning and transmission electron microscopy (SEM and TEM), taking care to prepare good samples for electron microscopy observations. These analyses provided values of APB densities for each sample, allowing to elaborate a phenomenological model concerning the growth and evolution of APBs, as a function of SiC thickness and substrate geometry.
Alessandro Meli has a master's degree in materials chemistry. After a series of work experiences, at STMicroelectronics and CNR-IMM, he started the doctoral course in materials science and nanotechnology, with a scholarship of ENI S.p.A. and in collaboration with CNR-IMM headquarter and INFN of Catania. The focus of the actual research is the study of Silicon Carbide (SiC) properties for power devices and particles detection applications, in particular for neutron detection in a thermonuclear reactor. SiC is a compound semiconductor which is considered as a possible alternative to silicon for particles and photon detection. Its characteristics make it very promising for the next generation of nuclear and particle physics experiments where the temperature and the radiation environment preclude the use of conventional microelectronic semiconductors. This study evolved from epitaxial growth on 4H-SiC substrates and related characterizations, up to continuing with the design and fabrication of the devices. The prototypes obtained will then be tested both electrically and with a neutron beam in order to simulate the operating conditions.
Mattia Pizzone è il vincitore di una borsa di dottorato industriale co-finanziata da CNR ed STMicroelectronics. I suoi interessi scientifici comprendono tecniche innovative di drogaggio su silicio (Si) e carburo di silicio (SiC). In particolare la sua attività scientifica riguarda il doping molecolare, una tecnica innovativa di drogaggio che utilizza molecole come mezzo per il trasporto di impurità sulla superficie del semiconduttore che, una volta iniziato il processo di drive-in, si scindono liberando il drogante e permettendone la diffusione all'interno della matrice del semiconduttore. La sfida principale del suo percorso di dottorato riguarda l'applicazione della tecnica al SiC e alle sue nanostrutture, notoriamente difficili da trattare con processi simili.
The research activity of Luca Pulvirenti is focused on the preparation of functional material through the surface modification of ferrites. It can be divided in two lines: synthesis of materials for: a) environmental and b) biomedical applications. Luca uses the photocatalytic properties of bismuth ferrite to degrade organic molecules that cannot be removed with classical removal methods while we will use the organic coating based on cavitands for the selective removal of pollutants (heavy metals and organic pollutants) present in traces in waste water. Luca is working on the development of two different materials in the treatment of wastewater and in anti-cancer therapies. As for wastewater, he is using the same inorganic core used for the treatment of pollutants, but with a different organic coating, in order to more effectively remove the bacteria that are often present in wastewater. For the second use, he is using the intrinsic biocompatibility and low toxicity properties of magnetite to design nanocomposites for drug delivery application with the aim of designing carriers that are able to protect anti-cancer drugs during the delicate passage of overcoming cell barriers.
Panasci Salvatore Ethan
My scientific interests cover the aspects related to the preparation and characterization of two-dimensional materials as Graphene and Transition Metal Dichalcogenides (2D TMDs) for micro and nanoelectronics applications. During my first two years as PhD student, I used a method developed by several groups in recent years defined “Mechanical exfoliation assisted by gold” by which is possible to prepare large area monolayers TMDs with high crystal quality. I also characterized these samples from morphological, electrical, vibrational and optical point of view by Atomic Force Microscopy (AFM), Conductive AFM, Raman and Photoluminescence Spectroscopy respectively. In addition, thanks to the ETMOS project collaborations, I characterized other 2D materials realized by Chemical Vapour Deposition (CVD), Molecular Beam Epitaxy (MBE) and Pulsed Laser Deposition (PLD). From these characterizations I learned to distinguish their electrical and optical differences even when integrated with wide-band gap materials (SiC and GaN).
I am Mario Pulvirenti PhD student in material sciences and nanotechnology. I have Master’s degree in chemistry of materials, obtained at University of Study of Catania. My doctoral activities and scientific interests are focused on synthesis and characterization of noble metal nanomaterials, having peculiar plasmon resonance properties. I am studying nanomaterial based on silver and gold which are the most interesting chemical species due to their strong plasmon properties. These nanoparticles are useful in many research fields as sensors, photo- catalysis and photovoltaic. Currently I am developing a specific sensor based on plasmon resonance and new methods to functionalize materials with silver and gold nanoparticles to create specific sensor substrates.
I am Marco Leonardi and I am a chemist. I deal with silicon photovoltaic technologies and the development of solutions to produce green fuels. I spent the last year characterizing silicon heterojunction bifacial solar cells and testing them in outdoor conditions in collaboration with the National Research Council and Enel Green Power. Furthermore, I have followed the design and realization of a water-splitting demonstrator made up of Silicon solar cells and a Polymer Exchange Membrane electrolyser that perfectly worked for six months. I am currently testing 4-terminal photovoltaic solutions based on Si and III-V semiconductors, e.g. GaAs, to increase modules' efficiency. In addition, I am working on ammonia production via electrochemical nitrogen reduction by using a no-noble metal catalyst.
My research interest focuses on Perovskite materials for thin-film Photovoltaic applications. It mainly relies on the interface coupling of the Perovskite absorber (e.g. MAPbI3) with the adjacent transporting layers (e.g. oxides) for the optimization of carrier extraction and transport in Perovskite Solar Cells. Special care is devoted to the stability of the device performances which is evaluated by electrical characterization under solar simulator over time (durability and ageing). As a step beyond, my research activity aims at investigating structure and stability of innovative Perovskites (e.g. CsPbI3, FASnI3) through the evolution of their optical and structural properties by in-situ advanced characterizations under controlled environment and temperature conditions.
