Thin film deposition and epitaxial growth systems are available at NFFA-Trieste for constructing complex materials and samples, e.g. digital heterostructures, on single-crystal substrates. Molecular Beam Epitaxy as well as Pulsed Laser-ablation Deposition offer competitive methods for in-situ single crystal thin films. E-beam sources and boat-type evaporators provide physical beams for submonolayer to few-monolayer thick deposits on surfaces at various kinetic conditions (down to cryogenic substrate temperatures) in all in-situ chambers and in-operando.

The core preparation and characterization facility of the NFFA-APE laboratory is a multicomponent UHV system. This facility is designed to serve as open platform to analyse and optimize nanoscience samples, for which the sample preparation and survey represent crucial and integral part of the experiment.

The NFFA laboratory is integrated with a synchrotron radiation beamline (Advanced Photoemission Experiment APE beamline), exploiting polarized synchrotron radiation in the ultraviolet and soft X-ray range from the Elettra storage ring. The low-energy beamline (APE-LE) covers 8-120eV photon energy range dedicated to high-resolution angle-resolved photoemission (ARPES) and spin-resolved ARPES; the high-energy beamline (APE-HE) covers 150-1600 eV photon energy range used for X-ray absorption (XAS), magnetic circular/linear dichroism (XMCD, XMLD), core level photoemission (XPS).
From 2018 users can require the use of SPRINT, the first pulsed laser beamline for time-resolved photoemission spectroscopy and spin polarization. The new endstation is addressed at the study of ultrafast magnetic processes in solid state physics by means of an upgraded vectorial Mott detector and a hemispherical electron analyser, suited to perform narrowband time-resolved valence band photoemission spectroscopy and spin detection.

The NFFA theory branch, by providing state-of-the-art first-principles simulations based on density functional theory, is mainly planned to support the interpretation of various experimental results obtained at other NFFA-Trieste labs. The main theory focus is on understanding microscopic mechanisms behind the observed phenomenology and investigating structure-property relationships or complex cross-coupling effects on different materials of interest. Following the comparison between theory and experiments, an “optimization” phase based on identifying guidelines and eventually performing “materials design” is available.

The European Commission encourages Open Science and FAIR data to improve and accelerate scientific research, to increase the engagement of society and to contribute significantly to economic growth.
All H2020 European projects that produce, collect or process research data are recommended to start dealing with the issues related.
NFFA-Trieste supports the principle of open data access as a fundamental part of its mission.
