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 40 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.

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.

Fine tuning of graphene-metal adhesion by surface alloy

We demonstrate how bimetallic surface alloying can provide a powerful, versatile tool to change the GR-substrate adhesion ad libitum by selecting the elemental composition of the substrate. The experimental approach we followed to grow graphene on a PtRu/Ru(0001) surface alloy can be readily extended to a number of other substrates.

Self-assembled Rh nanoclusters on graphene

Graphene-supported Rh nanocluster assemblies and their geometry dependent electronic structure have been studied  by combining high-energy resolution core level photoelectron spectroscopy, scanning tunneling microscopy, and density functional theory.

Influence of neighbouring atoms in Surface Core Level Shifts

We have shown that oxygen adsorption on Re(0001) induces the appearance of new core level components, whose binding energy is not simply determined by the coordination of the Re atoms, but, notably, is also affected by the presence of oxygen adsorbates at second and third nearest neighbour positions.

Destruction in the deep valleys

We have found a close relationship between morphology and thermal stability of epitaxial graphene. The highly corrugated C single–layer grown on Re(0001) undergoes C−C bond breaking in the buckled regions of the moirè cell, though it requires the presence of diffusing C vacancies.
