RESEARCH GROPUS

1.

Applied Surface Science And Vacuum Technology And Metrology

Group Leader: Orlando Teodoro

Labs: 244 and 246, Ed. 1

The goals of the Surface Science and  Vacuum Technology group may be outlined on the following topics:

• Surface supported nanoclusters and nanocatalysis
• Surface reactions, surface tailoring and ultrathin film growth
• Analysis of biological materials by surface analysis techniques
• Permeability evaluation and gas confinement
• Vacuum and ultra-low flow calibration

Research is mainly experimental and is supported by Time-of- flight Secondary Ion Mass Spectrometry (Tof-SIMS), X-Ray Photoelectron Spectroscopy (XPS), Auger Electron Spectroscopy (AES) and Low Energy Ion Scattering  (LEIS).

The group facilities includes the ISO17025 accredited laboratory— METROVAC, that offers calibration, testing and analytical services to the community.

Materials characterization for other research groups is routinely performed in the frame of scientific exchange.

Molecular Physics, Plasmas And Applications

Group Leader: Susana Sério

Lab: 123, Ed. 1

The Laboratory of Plasmas and Applications (LPA) was founded in 1994 by Professor Manuel Maneira, who was one of the founding members of CEFITEC.

The activity of LPA focuses on the experimental investigation of anomalous luminescent discharges in magnetron cathodes, the establishment of theoretical models for these discharges and in technological and industrial applications using the magnetron sputtering systems, for obtaining functional thin films.

The Atomic and Molecular Collisions Laboratory (LCAM - Laboratório de Colisões Atómicas e Moleculares) was founded in 2004 with the main goal on focusing the research activities and scientific cooperation on the electronic state spectroscopy of biological relevant, atmospheric (and aeronomic) and the semiconductor industry molecules, radiation effect in biological systems as well as negative ion formation by electron transfer processes in atom(potassium)-(bio)molecule collisions.

At the moment the research motivations are on the VUV electronic state spectroscopy by synchrotron radiation, negative ion yields by electron attachment in the gas phase and electron stimulated desoprtion in the condensed phase with low energy electrons (<20 eV) and electron scattering of biological relevant and aeronomic molecules, the latter including global warming, ozone depletion and seeking environmentally friendly molecules for plasma processing. Other current research interests are the reactivity of co-adsorbed species in ices in the interstellar medium.

Functional Molecular Systems

Group Leader: Maria de Fátima Raposo

The research activity has been focused on the research of the physical-chemical features of surfaces and interfaces of organic and biologic macromolecules leading to the build-up of self-organized organic molecular structures for the creation of molecular electrical, optical, photonics and sensing devices. The research cover the following aspects:

• Physical-chemical interfacial phenomena at the solid-liquid interface - adsorption from solution, at a solid-liquid interface, theory and modelling;
• The physics of surfaces and interfaces of macromolecules, concerning the mechanisms giving rise to the attainment of super-lattice structure that emphasizes a determined function;
• Characterization of functional proprieties of surfaces and interfaces, its structural relaxation behaviour and relation with interface environment;
• Build-up and characterization of self-organized molecular structures concerning surface morphology, electrical, optical, magnetic functional proprieties and particular sensing capabilities;
• Device production, involving development of dedicated lithography, housing, interfacing and figure of merit evaluation reliability and relaxation behaviour;
• Membrane mimicking and radiation damage on biomimetic membranes.
• Development of dedicated scientific apparatus for in-situ monitoring molecular surfaces and interfaces, namely based on optical spectroscopy, optical birefringence second-harmonic generation, electro-optic effect, piezolelectricity, ellipsometry.
