 Scientific Background:

Dr.Orgiani was born in Naples, Italy, in 1975. He took his bachelor degree in Physics at the University of Naples in 1999. Then he achieved the Ph.D. in Microsystems Engineering at the University of Roma Tor Vergata in 2002. He is a researcher at CNR-IOM (National Research Council institute for Materials Foundry), located at Area Science Park campus in Trieste in the field of deposition and characterization of oxide manganite and superconducting thin films.

At the beginning of his activity he worked on microwave properties of high temperature superconducting YBCO. In particular, he took apart to a project finalized to the realization of a prototype of a pass-band filter for commercial mobile telecommunication in collaboration with the industrial world (i.e. Omnitel s.p.a.). During the PhD thesis work, he focused his attention on fundamental transport mechanism in high temperature superconductors, in particular in the Infinite Layer compounds grown in form of superlattices by conventional Pulsed Laser Deposition. On the other hand, he was also involved in the realization and study of physical properties of other functional oxide materials (ferromagnets, insulators, etc.) grown by Laser Ablation deposition technique equipped with in-situ RHEED analysis.

On 2004, he worked at The Pennsylvania State University on the newly discovered superconductor magnesium diboride MgB2. For both fundamental studies and electronic applications of the magnesium diboride superconductor, it is mandatory  to have high-quality single-crystalline thin films with intrinsic superconducting and normal-state properties. In order to achieve such a result, an innovative hybrid physical–chemical vapor deposition (HPCVD) technique was developed a few years before at Pennsylvania State University, which combines physical vapor deposition (PVD) with chemical vapor deposition (CVD). Still today - on 2022 – the quality of the MgB2 films grown by such an HPCVD are the state-of-the-art with respect the synthesis of the magnesium diborade in different forms (e.g. film, coating, fibers, and so on). On 2005, he moved – as scientist - to the Coherentia INFM Research and Development Center (merged in CNR on 2010) in Salerno to project-and-build a thin film deposition system based on the Pulsed Laser Deposition. At the same time, he responsibility of the existing Molecular Beam Epitaxy system and the laboratory for the investigation of the magneto-transport properties of thin films. During these years a strong activity on electronic investigation (i.e. x-ray absorption spectroscopy, x-ray photo-emission spectroscopy and angular-resolved photoemission spectroscopy) has been initiated by Dr.Orgiani at several synchrotron radiation facilities (in particular at ELETTRA in Trieste and E.S.R.F. in Grenoble - France).

On 2015, he has been put in charge of a research program aiming to the building of a thin film deposition facility directly connected to a synchrotron beamline. Such a system based on Pulsed Laser Deposition, operative since 2015, is currently part of the available techniques within the NFFA-Trieste project which offer an open-access program for nano-science and fine analysis (http:www.trieste.nffa.eu).

Recent Scientific Activities: 

Nowadays, Dr.Orgiani is staff scientist at CNR-IOM institute in Trieste and head of DIGIMAT (DIGItal growth of quantum MATerials) laboratory. The main activity is the deposition of complex materials and heterostructures in form of thin films and the investigation of their electronic and structural properties. He masters the structural and stoichiometric characterizations of thin films and heterostructures by X-ray diffraction system, Scanning Electron Microscopy and Energy Diffraction x-ray Spectroscopy.  His research on complex materials and heterostructures is focused on the role of structural properties (mainly strain induced on the thin films by different substrates during the epitaxial growth) on the electronic properties (e.g. metal-insulator transition, topological properties, 2-dimensional electron gas, quantum interference effects at low temperatures, and so on) of such compounds.
