Surface Science Laboratory


Welcome to the Surface Science Lab

The SURFACE SCIENCE Laboratory, jointly established on the basis of an official agreement by the Department of Physics of the University of Trieste and Elettra - Sincrotrone Trieste, hosts researchers and students carrying out experimental activities in the field of Surface Physics, in close collaboration with scientists from the Elettra Laboratory. Since 2000 more than 60 students have carried out experimental work at the Surface Science Laboratory in preparation of their Master's degree thesis in Physics, as well as in the framework of the PhD educational program of the Doctoral School of Physics and the Doctoral School of Nanotechology of the University of Trieste. In addition the Laboratory hosts the Training Activity of the course Laboratorio di Fisica della Materia for the undergraduate students in Physics at the University of Trieste.

Epitaxial graphene boosts photocatalysis in titania nanoparticles

The choice of an interfacial layer of epitaxial graphene to support titania nanoparticles has been revealed as a key ingredient to dramatically increase their capability to split water and produce hydrogen.

It's a matter of transparency to van Der Waals forces

The van der Waals interactions between light adsorbates with polar (Carbon Monoxide) and non-polar (Argon) character and a metal surface are partially screened by graphene which shows a translucency parameter equal to 0.507.

The role of carbon monomers and dimers in graphene growth

We show that the growth kinetics are controlled by a complex interplay between the diffusion of the carbon precursors on the growing graphene islands and their desorption.

Molecular twisting, lifting and curling

Coronene molecules undergo major conformational changes during surface-assisted dissociation on Ir(111): they tilt upward, then they undergo  a rotation and they settle to form a dome-shaped nanographene.

Bottom-up approach for the synthesis of graphene-alumina nanosheet interfaces

We developed a new strategy for the production of graphene-oxide interfaces which opens a promising route to the direct synthesis on a number of graphene/high-κ dielectrics interfaces.

Chemistry vs geometry: the role of the substrate on epitaxial graphene

Ina a combined experimental and theoretical work we have demonstrated that the chemical composition of the substrate's topmost atomic layer plays a major role in determining the coupling between epitaxial graphene and its metal substrate.

The thinnest carpet on the smallest atomic staircase

We have grown a single-layer graphene on a stepped Rh(533) surface. The geometry of the substrate leads to an anisotropic moirè cell with the steps playing a key role in improving the structural quality and thermal stability of the carbon layer.

Graphene growth: the surface battle of Carbon

We shed light on the complex interplay between competitive processes occurring during chemical vapour deposition of ethylene on Re(0001). Our results demonstrate that the formation of a long-range ordered graphene layer  is confi ned to a very narrow window of growth parameters.
