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.

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 NFFA offer includes a facility for spectroscopic investigation of solid surfaces and nanostructured matter. 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. Photons with chosen polarization are emitted by Apple II insertion devices. 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).

NFFA-Trieste is creating the first prototype of Data Repository in
nanoscience, to be further developed under NFFA-Europe. This repository aims at recording all relevant metadata for a given nanoscience project, including growth/nanofabrication protocols so that the reproducibility of preparations and experiments will enable to compare complementary data obtained with different methods on valid replica samples and controlled environment conditions. In the current test-phase the repository will provide an advanced service to store all data produced at NFFA-Trieste facilities. The data repository and data management system is jointly developed by IOM-CNR and KIT (Karlsruher Institut für Technologie), based on the KIT Data Manager technology. The generic service stack provides enough flexibility to support various scientific communities and user types in a modular and extensible way.

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.
