Our research activity involves the theoretical simulation of the structural, electronic, optical and transport properties of materials, surfaces, interfaces and nanostructures.

Theoretical frameworks

  • ab-initio density functional theory (DFT)
  • maximally localized Wannier functions (MLWFs) calculation
  • semi-empirical tight binding (TB)
  • effective-mass approximation and other effective models

Research tools

  • Quantum ESPRESSO: an integrated suite of computer codes for electronic-structure calculations and materials modeling at the nanoscale. It is based on density-functional theory, plane waves, and pseudopotentials
  • Wannier90: a computer package for the computations of the maximally localized Wannier functions
  • NWChem: a computer package for computing the properties of molecular and periodic systems
  • Yambo: a computer package for many-body calculations in solid state and molecular physics

Main research topics


Spin-polarized quantum conductance of randomly hydrogenated zigzag graphene nanoribbons

Electronic and transport properties of graphene


Methods: DFT - MLWFs
Short description: we study the electronic and transport properties of graphene, graphene nanoribbons and carbon nanotubes from first principles. Special attention is given to the effect of the presence of defects and of (edge or bulk) functionalization.

A model of a TiO2 (anatase)-SrTiO3 interface

Metal oxide surfaces and nanostructures


Methods: DFT
Short description: we study the structural, electronic and optical properties of: TiO2, SnO2 and ZnO surfaces; TiO2 nanowires and nanocrystals, for sensor applications, photocatalysis, new generation solar cells. Among the results, we cite: the role played by the size and surface passivation in TiO2 nanostructures; the theoretical assessment of the TiO2 (110) surface reconstruction; the explanation of the photoluminescence spectra of SnO2 nanobelts.

Organic coverage of the silicon (100) surface

Organic adsorbates on semiconductor/metallic surfaces


Methods: DFT
Short description: We have studied the covalent modification of the silicon (100) surface from first principles. Ethylene, cyclopenthene and a class of its derivatives have been chosen as test cases to correlate the surface structural and electronic properties changes to the properties of the adsorbate. The results show the possibility of surface properties (e.g. work function) engineering through a suitable choice of the adsorbate. Currently, we are extending our study to metal/organic interfaces.

Semiconductor nanocrystals


Methods: DFT, Tight Binding, Thomas Fermi
Short description: The structural and the optical properties of silicon nanocrystals are investigated with both the DFT and the tight binding methods. Doping and codoping together with the screening of the impurity potentials are studied with both DFT and Thomas Fermi.
