Nanomaterials and advanced characterization

O

New developments in the modeling and analysis of radiation damage in materials II

Nowadays, it is common to find technological environments subject to irradiation with energetic particles, such as for instance materials in spintronics, semiconductors, space applications or nuclear reactors. This particle/matter interaction strongly affects the properties of the materials. This symposium will provide a forum to discuss the latest development in the characterization and modeling of particle/solid interactions.

Scope:

The use of particle (ions, photons, neutrons, protons...) beams over a broad range of energies is a powerful tool to synthesize, test, and modify the properties of advanced materials. On the other hand, there also exist technological applications subject to undesired energetic particle fluxes that strongly degrade their performances. Research and applications of energetic particle beams encompass, among others, advanced electro-optical devices, nanostructures, strain engineering, nuclear materials, and space exploration. In most cases, particle beam modification of materials relies on the energy transfer from the energetic particles to atomic nuclei and/or electrons of the target. Usually, the deposited energy leads to defect generation and damage accumulation. These phenomena are sometimes desired, e.g., to simulate radiation environments such as those encountered in space and nuclear reactors; but they may also be a drawback, for instance in ion doping processes, or in the synthesis of nanostructures. In any case, understanding the mechanisms of damage formation and accumulation in materials as a result of energy deposition under irradiation is a crucial task to tackle.

This symposium is the follow-up of the 2018 edition which took place during the E-MRS Spring meeting and gathered ~ 60 scientists (speakers + posters) from more than 10 countries around the world. The aim of this symposium is therefore to provide a forum for researchers to present and discuss the developments and improvements of experimental characterization techniques, computational tools, theoretical models and codes for data fitting in the field of radiation damage. Special focus will be given to techniques, protocols, and methodologies allowing damage quantification. The coupling of experimental and computational characterizations will also receive particular attention. Finally, recent progress in in situ measurements, small-scale testing as well as improvements of conventional techniques to investigate radiation damage will also be addressed. To finish, this symposium is cross-disciplinary on a wide range of materials including metals, semiconductors, and iono-covalent materials with different dimensionality (e.g. 0D quantum dots, 1D nanowires or tubes, 2D thin film materials and 3D bulk materials) and on a broad range of irradiation conditions, experimental techniques and computational simulations.
