PhD program

Multiscale modeling of high energy irradiation in semiconductors

PhD supervisors: Pedro López and Lourdes Pelaz.

The recent semiconductor crisis has highlighted our world's dependence on these components that surround us at home and in our cities, and make possible the most advanced developments in nanotechnology, astrophysics, and particle physics. Advances in manufacturing technology for new semiconductor integrated circuits as well as their operation (in satellites, in nuclear physics, at CERN, etc.) involve subjecting semiconductors to high-energy irradiation. The interaction of energetic particles with the semiconductor lattice generates defects that degrade its performance. It is complex to associate measurable macroscopic effects with their microscopic origin, but this knowledge is essential for device optimization. The PhD student will use several atomistic simulation techniques (ab-initio, molecular dynamics, binary collision approximation, kinetic Monte Carlo) in a multi-scale scheme to study from fundamental properties of defects to the dynamics of the irradiated system in macroscopic dimensions and times comparable with experiments.

The PhD program has several aims:

  • The development of improved irradiation models that extend the range of use of the binary collision approximation: both for low-energy recoils produced by light particle irradiation, where multiple collisions are relevant; as in high energy irradiation where the energy transferred to the electronic system is significant.
  • The simulation of the dynamics of the defects and impurities produced by the irradiation of particle detectors, and compare them with the macroscopic effects.
  • The quantum mechanical characterization of the defects produced by irradiation to clarify their electronic effect on irradiated devices.

All the research activities will be directly supervised by Pedro López and Lourdes Pelaz, although the candidate will closely interact with all the members of MMM group.

This PhD program is directly enrolled within active resarch projects of MMM group.
